clutter: Honor pick vmethod rectangle during region caching

We retrieve the picked actor's allocation for figuring out the pick
cache clear area, but don't take into account that the pick vmethod
might have returned a different area for it.

Make sure to honor that rectangle, as that is what is accounted as
the input region.
