Override drawRRect in fake SkBitmapDevices.

Recent changes to SkBitmapDevice modified ::drawRRect() to take an
optimized drawing case (currently hidden behind a flag). Some
subclasses of SkBitmapDevice were depending on the old behavior of
calling ::drawPath(). Since they do not draw, attempting to take
the drawing path can cause problems. For these subclasses, call
drawPath in the subclass.
