Disallow interception of multitouch events

Browse Source 
The shade mishandles multitouch events when the first touch
originates in the status bar, which results in the second touch
being an ACTION_DOWN instead of ACTION_POINTER_DOWN. This causes
multiple problems, so it's preferable to not intercept these
events when we detect them.
