Subject: tests/profpatsch/programs/nman: add nixos test for nman

We can't really do normal unit tests, since they'd be integration tests
requiring nix. Recursive nix is also a bad idea in normal derivations,
so we add a NixOS test for nman.

Here we are also somewhat limited since we already need to have all
store paths used by nman in /nix/store otherwise we'd need to access the
network which would fail. However we can verify that nman only builds
specific store paths before finding the desired man page this way.
