cbfstool: Change FMAP granularity to 16 bytes
Instead of looking for an FMAP at every byte, only search down
to a granularity of 16 bytes, reducing the time for a cbfstool
call by 0.3s when no FMAP is found.

BUG=none
BRANCH=none
TEST=time ./cbfstool coreboot.rom add -f locale_de.bin -n locale_de.bin -t 0x50 -c lzma
is 0.3s faster than before.
