make_factory_package: add --usbimg for USB installation images
To make "USB installation image" (useful for RMA images), make_factory_package
now supports --usbimg and --install_shim for the new type of image.
Some internal refactoring is also included in this CL to ease adding new
generation methods.
BUG=chrome-os-partner:4108
TEST=make_factory_package --usbimg rma.bin --factory PATH_TO_FACTORY \
--release PATH_TO_RELEASE --install PATH_TO_INSTALL_SHIM
# then turn on developer switch, hold recovery button to boot by the
# rma.bin. Seeing installation from USB works fine.
