Modify the installation rules of sh binary based on the image variants

This change modifes the build rules of sh binary module type so that:
- The installation paths respects the image variations and the
  *_available properties.
- The androidmk entries have subnames so that the names of the different
  variants do not collide.

Test: Patch ag/27004177 and run m nothing
