    screenShield: Don't inhibit suspend during initial setup
    
    Normally, we inhibit suspend while locking the screen. But in the
    session mode used for gnome-initial-setup locking is not supported, so
    in that case this inhibit call is pointless and should be avoided.
    Without this patch you get the following error when you suspend and
    resume during initial setup:
    
    JS ERROR: Error getting systemd inhibitor: Gio.IOErrorEnum:
    GDBus.Error:org.freedesktop.login1.OperationInProgress: The operation
    inhibition has been requested for is already running
