util/cbfstool: Enable adding precompressed files to cbfs

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.
