54ece050b8 nixos/qemu-vm: default memorySize 384 -> 1024
the default hasn't been changed since 2009
this can improve our test performances

nixos/tests: remove explicit memorySize <1024

1024MiB is now the default

nixos/tests/{sway,cage,cagebreak}: Fix the tests on aarch64-linux
Since the update to wlroots 0.13 (e03dde82a7) the default VGA card
isn't supported anymore and we needed to switch to virtio (qxl didn't
work either). However, as it turned out "-vga virtio" (28b8cff301)
broke the test on AArch64. Luckily there's a third option that works on
all three supported platforms: virtio-gpu-pci

According to [0] "This device lacks VGA compatibility mode but is
otherwise identical to the virtio vga device. UEFI firmware can handle
this, and if your guests has drivers too you can use this instead of
virtio-vga. This will reduce the attack surface (no complex VGA
emulation support) and reduce the memory footprint by 8 MB (no pci
memory bar for VGA compatibility). This device can be placed in a PCI
Express slot."
So in the end this seems like the ideal choice :)
See also [1].

nixos/tests: Replace QEMU_OPTS usages with virtualisation.qemu.options
See [0]: "QEMU_OPTS is something that should be set by people running VM
tests interactively, to do port forwardings etc.
We really should not poke with it from the test script - that's what
virtualisation.qemu.options is for."

nixos/tests/cage: Fix the test with wlroots 0.13
See #119615 for more details. The aarch64-linux test failed with
"qemu-system-aarch64: Virtio VGA not available" so I've restricted the
test to x86_64-linux (the virtio paravirtualized 3D graphics driver is
likely only available on very few platforms).

nixos/tests/cage: Increase the xterm font size to fix the test
The result still looks far from ideal but at least it gets recognized
now. "-fa Monospace" is required to switch to a font from the FreeType
library so that "-fs 24" works.

Note: Using linuxPackages_latest is not required anymore.

cage: drop maintainership (#121174)
I cannot currently maintain this, as I don't have access to the hardware
running it anymore.

25bef2d8f9 treewide: simplify pkgs.stdenv.lib -> pkgs.lib
The library does not depend on stdenv, that `stdenv` exposes `lib` is
an artifact of the ancient origins of nixpkgs.

e0e4d591cc nixos/cage: init
Add a cage module to nixos. This can be used to make kiosk-style
systems that boot directly to a single application. The user (demo by
default) is automatically logged in by this service and the
program (xterm by default) is automatically started.

This is useful for some embedded, single-user systems where we want
automatic booting. To keep the system secure, the user should have
limited privileges.

Based on the service provided in the Cage wiki here:
