x11: Add a hack to detect touch-cancel events from X11.
The touch-end event chrome receives from X does not contain enough
information to know whether the event came because the user lifted
the finger, or something else happened in the system that triggered
the event. So add some hack to figure out whether to generate a
touch-release event or a touch-cancel event from the X touch-end event.
