Override drawRRect in fake SkBitmapDevices.

Recent changes to SkBitmapDevice modified ::drawRRect() to take
an optimized drawing case. 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.
