[Android] Ripple control block scrolling

[takla21]

Current behavior

When there's Ripple control inside the scrollviewer (for instance itemtemplate of a itemscontrol) it's harder to scroll, because the ripple control intercept the scrolling.

Expected behavior

We should be able to scroll smoothly no matter if there's a ripple control or not.

How to reproduce it (as minimally and precisely as possible)
