Add several workaround needles for RHBZ#1933378
    
    There's a bug in F34/Rawhide lately where the bootsplash isn't
    fully cleared when displaying text consoles, this causes all the
    login needles not to match. Add several workarounds to make the
    most common cases at least work with the bug, failing on it is
    not much use.
