Apply "most-recent" delivery policy to ACTION_USER_RESTRICTIONS_CHANGED.

Browse Source 
This allows us to skip any older ACTION_USER_RESTRICTIONS_CHANGED
broadcasts waiting to be delivered when a new broadcast is dispatched.
It should be safe to discard the older ones as the broadcast is only
indicating that something has changed.
