[Android] Photo Picker: Fix white circle overlay regression.

A recent refactoring of SelectableItemView[Base] introduced
a regression where a white selection circle would show on top
of all images in the Photo Picker.

The fix is to switch inheritance from SelectableItemView to
SelectableItemViewBase, which doesn't inflate any extra xml.
