exo: Replace fling cancel with generic zero distance scroll

This change will suppress all fling cancel events unless the last event
was a fling event. Also it generates a proper sequence of a scroll
event with zero distance.

BUG= 590754 
TEST=Fling and touch the touchpad after fling. Should stop scrolling
motion in android apps.
