[x11] Create barriers only when grabbing
While using barriers is a zillion times better than actually grabbing the mouse and keyboard, they're still a pain when debugging as qf is not able to respond to the barrier-hit events. All the other logic is still there so even when "grabbing", the mouse will not be blocked if the window doesn't have focus.
