remove sysutils/nix

Efforts to get nix(pkgs) going on OpenBSD seem to have been dropped
completely, I stopped using our port looong ago and, since import in
2023, have never received a single report from anyone.

Some things never worked, others require bits in nixpkgs to be done,
which never happened.

Is anyone using this in any capacity other than 'toying with ideas'?

If not, I'd like to drop it for real and give back some bulk time.

Feedback? OK?

6 is "no longer usefel".
