Breaks make_image_bootable out of build_image into a separate
script. In addition, it make a helper .sh in the OUTPUT_DIR
to let make_image_bootable be re-run on an image with the same
arguments that were passed in via build_image.
This change also removes the use of the boot/ directory in
OUTPUT_DIR.
