Tweak user_logged_in needles a bit
    
    Matching on the user name really isn't doing much good. It just
    means we need more variant needles. Let's ditch that part of the
    match and just match on the distinctive character sequence ~]$,
    which doesn't really occur for any other reason. With this we
    can drop the separate 'qwerty' needle (since the qwerty case
    will match the regular needle now) and should also handle the
    FreeIPA tests that are failing in Rawhide because a logged in
    FreeIPA user doesn't just have a sh prompt now.
