    libgames-support: Only build games-setgid-io when --enable-setgid
    
    Add some #ifdefs to games-scores-backend to only use setgid IO when it's
    enabled in configure, and only then build games-setgid-io.[ch].
    Should fix bug #445270, but of course scores are not working at all with
    --disable-setgid, as before.
