feat(naersk): use naersk to build packages with rust

naersk makes it simple to build rust project in nix.

For this to work, `mkSystem` and `mkHomeManagerConfiguration` needs to
pass naersk to  my overlays.

I dropped the support to run the tools with `nix run .#tools...`: I
don't use this in practice and it's not making things simpler.

I dropped `nix-linter` from the check, it's reporting many errors
without helping me to fix them.
