Fix toggle QS tiles don't respond when One-handed mode triggered

Previous ag/17896369 missed the OHM edge case, when OHM
activated, the ev.getX(), ev.getY() has been count in OHM

the QQS tile location while OHM translate down DisplayArea.

1. Set x and y offset for mQsHeaderBound when OHM activated
2. Fix broken NotificationStackScrollLayoutTest
