vibrator: Add a threshold to filter out some short vibration cases 

Some app will use short vibration to implement haptics effect and
those cases will feel a delay from the motion awareness mechanism.

We add this patch to filter out those cases since those behaviors
beyond the motion awareness mechanism scope.
