Convert VM tests to Python

Browse source 
Perl-based tests are deprecated since NixOS 20.03 and subsequently got
removed in NixOS 20.09, which effectively means that tests are going to
fail as soon as we build it with NixOS 20.09 or anything newer.

I've put "# fmt: off" at the start of every testScript, because
formatting with Black really messes up indentation and I don't think it
really adds anything in value or readability for inlined Python scripts.
