cbfstool ... add ... -c precompression assumes the input file to be
created by cbfs-compression-tool's compress command and uses that to add
the file with correct metadata.
When adding the locale_*.bin files to Chrome OS images, this provides a
nice speedup (since we can parallelize the precompression and avoid
compressing everything twice) while creating a bit-identical file.
BUG=chromium:630451
BRANCH=none
TEST=with the necessary tweaks to the build system,
emerge-kevin chromeos-bootimage takes 0:25 instead of 3:10 before on the
z620 I work on, about a magnitude faster.
