test: Add rudimentary support to run selected tests only

Browse Source 
To keep this simple, only support tests that have corresponding setup
and teardown functions implied by their path. For example:

  ./run passt/ndp

will trigger the 'passt' setup and teardown functions.

This is not really elegant, but it looks robust, and while David is
considering proper alternatives, it should be quite useful.

## Running selected tests
Rudimentary support to run a list of selected tests, without support for
dependencies, is available. Tests need to have a setup function corresponding to
their path. For example:
./run passt/ndp passt/dhcp pasta/ndp
will call the 'passt' setup function (from lib/setup), run the two corresponding
tests, call the 'passt' teardown function, the 'pasta' setup, run the pasta/ndp
test, and finally tear down the 'pasta' setup.
Note that requirements on steps implemented by related tests are not handled.
For example, if the 'passt/tcp' needs guest connectivity set up by the
'passt/ndp' and 'passt/dhcp' tests, those need to be listed explicitly.
