nixos: flesh out the grsecurity test suite

I've failed to figure out what why `paxtest blackhat` hangs the vm, and
have resigned to running individual `paxtest` programs.  This provides
limited coverage, but at least verifies that some important features are
in fact working.

Ideas for future work includes a subtest for basic desktop
functionality.
