mb/google/skyrim/var/skyrim: Hide fingerprint reader from Windows OS

No Windows driver exists or is needed, so hide to prevent an unknown
device from being listed in Windows Device Manager. Same change was
made for frostflow variant previously.

TEST=build/boot Win11 on skyrim, verify unknown device for the
fingerprint reader no longer present.
