xwayland: Handle race between multi-pointer motion and clicks

Browse Source 
Make sure we're looking at the right location.  The frame could have
received a motion event from a pointer from a different wl_seat, but
under X it looks like our core pointer moved.  Move the frame pointer
to the button press location before deciding what to do.
