Add needles to handle console login with 'white on grey' colors
    
    https://bugzilla.redhat.com/show_bug.cgi?id=1403365 has been
    around approximately forever and I still haven't managed to
    debug it; let's just make needles for it, as it's not really a
    critical bug, the system still *works*.
