    gdm: Remove separate greeter universal access icon
    
    The idea behind always showing the icon on the login screen is that
    the users' needs aren't known at that point. However we can achieve
    the same behavior by including the 'always-show-universal-access-status'
    key in GDM's presets, so drop the special-case.
