nixos/test-driver: accept non-\w* filenames 
What the code was trying to do was helpfully add a directory and
extension if none were specified, but it did this by checking whether
the filename was composed of a very limited character set that didn't
even include dashes.

With this change, the intention of the code is clearer, and I can put
dashes in my screenshot names.

nixos/test-driver: handle decoding errors in Machine.execute 
The output of a command is not guaranteed to be valid UTF-8, so the
decoding can fail raising UnicodeDecodeError. If this happens during a
`succeeds` the check will be erroneously marked failed.

This changes the error handling to the "replace" mode, where invalid
codepoints are replaced with � (REPLACEMENT CHARACTER U+FFFD) and the
decoding can go on.

nixos/test-driver: drop logging from Machine.send_monitor_command 
Several machine operations, like `send_chars` and `send_key`, are
implemented by calling `send_monitor_command`, possibly multiple times.
This generates a huge amount of unnecessary noise in the log, because
`send_monitor_command` is a low-level operation and an implementation
detail.

Here's an excerpt from a highlighted log before and afte the change.

29db54c373 nixos/tests: extend shell_interact to accept alternative socat addresses 
`shell_interact()` is currently not nice to use.  If you try to cancel
the socat process, it will also break the nixos test. Furthermore
ptpython creates it's own terminal that subprocesses are running in,
which breaks some of the terminal features of socat.
Hence this commit extends `shell_interact` to allow also to connect to
arbitrary servers i.e. tcp servers started by socat.

nixos/test-driver: add wait_for_unit() timeout arg 
For example, the wait_for_unit() call in the Moodle test times out for
myself and others[1], so it would be good to be able to increase it to
something less likely to be hit by a test that would otherwise pass.

f6a290932e use vde switch in hubmode by default 
Within a dual VM test-setup a strange behaviour was observed.
The two VMs are connected via one vde_switch instance
(instancevirtualisation.vlans = [ 1 ]; IMO a bad attribute name for
switch instances, has nothing to do with VLANs in sense of 802.1Q).

A ping on the base interface (eth1) works, but not on VLAN
subinterfaces (vlan1@eth1). A tcpdump of eth1 includes the ARP requests
tagged with the subinterfaces VLAN ID, but responses seems not to pass
the vde_switch. This works fine if performed on the base interface.

Putting the vde_switch in hub mode results in flooding
traffic to all vde_switch ports. This results in a expected behaviour
and a ping on a VLAN subinterface works as expected.

f7e89a59da nixos/test-driver: fix missing shellopts in execute 
Without this fix, setting the shellopts in `machine.execute` is
inconsitent.  When no timeout is used, shellopts `set -euo pipefail` are
applied to the command as expected. When a timeout is specified, the
shellopts are not applied to the command itself (which is called inside
a `sh -c` that doesn't inherit the shellopts) but rather to the
`timeout` command, leading to the following full command:

```bash
(set -euo pipefail; timeout 900 sh -c 'cmd') | (base64 --wrap 0; echo)\n
```

With this fix, this is the command we get:

```bash
timeout 900 sh -c 'set -euo pipefail; false | true') | (base64 --wrap 0; echo)\n
```

nixos/test-driver: highlight driver log lines 
There is a whole lot of noise in a NixOS test log due to journal,
commands, and test driver messages all being mixing together.
With this commit the test driver messages are highlighted so you don't
have to squint too much to see where a subtest starts and ends or what
was the last command being run.

Here's an excerpt from a highlighted log:

nixos/test-driver: deduplicate VLANs 
Naively deduplicate VLANs in the python driver for NixOS tests. The
current implementation accidentally works, since the VLan class mutates
the environment. On construction it sets QEMU_VDE_SOCKET_${id} and this
environment variable gets overwritten once a second VLAN with the same
id is constructed. Because the NIC flags passed to qemu just use the
QEMU_VDE_SOCKET_${id} environment variable, this implicitly chooses a
single vde_switch process for each VLAN.

However, this leads to unusable vde_switch processes being spawned in
each test run and as a side effect makes it impossible to access the
correct VLan objects in the interactive test driver. It also makes it
remarkably hard to understand why the current implementation ever
worked.

24fb872079 nixos/test-driver: fix regression when using legacy start command 
The aarch64-linux versions of the boot.uefiUsb and boot.uefiCdrom tests
were broken by b0fc9da879.
That commit was a refactor which omitted the qemuBinary option, which was
previously available in the legacy start command. This restores that
option and fixes the tests previously mentioned.
