util/crosfirmware: Add support for parsing from manifest.json

Browse source 
Some ChromeOS recovery images, such as for GRUNT, support multiple
boards / multiple bios/ec images, but do not break them out in a
'models' subdirectory like modern recovery images do. Instead,
they use a manifest.json to map the board name to the correct
bios/ec images. Add support for parsing out the info from here.

TEST=run `util/chromeos/crosfirmware.sh kasumi` and verify
that the correct shellball firmware is extracted from the recovery
image.
