Set the hover state to the same as focus state in RippleDrawable.

Bug 24810682

There was no hover state for bounded ripples and it was decided
that a solid background color exactly like the focus state
was desired. This change triggers the RippleDrawable to act as
if it is focused when it is hovered.
