xcb: Fix TouchPointPressed being sent multiple times.

XI2 sends events for individual touch points, but QTouchEvent
sends all of them with a stationary state if they didn't change.
If a touch pressed event is received, and the next XI2 event
is about a different touch point, we wouldn't update the state
of the previously pressed touch point.
