    unlockDialog: Honor switch user lockdown settings
    
    At the moment user switching functionality is controlled by two
    settings:
    
    org.gnome.desktop.lockdown disable-user-switching
    
    for the panel when the session is unlocked, and
    
    org.gnome.desktop.screensaver user-switch-enabled
    
    for the unlock dialog when the session is locked.
    
    Having the lockdown setting not apply when the screen is
    locked is counterintuitive.
    
    This commit makes the unlock dialog honor both settings.
