NixOS build checks significantly slowed down `nix flake show` as it prints out the derivation names, which for NixOS derivations requires a large amount of evaluation. By wrapping the derivations, we now give them trivial names. The NixOS configurations are still built when running checks as they are a dependency of the wrappers.
