nixos/udev: compress firmware with zstd if possible
Closes #267442

    $ nix path-info -Sh /nix/store/qj1dm7wfw5m3mxf1gn3fdm0az9y1h5ny-linux-firmware-20240312-xz
    /nix/store/qj1dm7wfw5m3mxf1gn3fdm0az9y1h5ny-linux-firmware-20240312-xz	440.3M
    $ nix path-info -Sh /nix/store/c3szcjxb3g990dbiz7llwmkaf0bi98j2-linux-firmware-20240312-zstd
    /nix/store/c3szcjxb3g990dbiz7llwmkaf0bi98j2-linux-firmware-20240312-zstd	460.6M

This is an increase of 4.4%, but OTOH zstd has a significantly higher
decompression speed[1].
