nixos: Add rudimentary VM tests for Chromium.
Currently, the test is only for testing the user namespace sandbox and
even that isn't very representative, because we're running the tests as
root.

But apart from that, we should have functionality for opening/closing
windows and the main goal here is to get them as deterministic as
possible, because Chromium usually isn't very nice to chained xdotool
keystrokes.

And of course, the most important "test" we have here: We know at least
whether Chromium works _at_all_.
