make_factory_package: support using firmware updater from release rootfs

Browse Source 
For most use case, we want to use the firmware updater from release image
rootfs. It'd be more convenient if make_factory_package extracts updater from
release image by default.

BUG=chromium-os:21512
TEST=./make_factory_package --release RELEASE --factory FACTORY --hwid none
     # success, seeing "firmware: XXXX" in output
     ./make_factory_package --release RELEASE --factory FACTORY --hwid none --firmware none
     # success, not seeing firmware in mini-omaha configuration
     ./make_factory_package --release RELEASE --factory FACTORY --hwid none --firmware FIRMWARE
     # success, seeing "firmware: XXXX" in mini-omaha configuration
     ./make_factory_package --release RELEASE --factory FACTORY --hwid none \
       --diskimg ssd.img
     # success, no firmware messages
     ./make_factory_package --release RELEASE --factory FACTORY --hwid none \
       --diskimg ssd.img --firmware FIRMWARE
     # failure as expected - firmware is not supported in --diskimg.
