chore: remove Nix flake

Problem: The committed Nix flake is not used by the standard tooling in
this repo and therefore bitrots freely, which increases maintenance
burden on the (non-Nix-using) maintainers. We also don't maintain
packaging for other distros in-repo.

Solution: Drop the Nix files from the repo and (as follow-up) move the
Nix packaging to an out-of-core project.
