    stylix: make nix-flake-check package execution location-independent

    Make the execution of the nix-flake-check package independent of the
    current working directory, making the following command work as
    expected:

        nix run github:danth/stylix#nix-flake-check

    This is especially convenient for testing PRs locally without checking
    them out.
