util/cbfstool: add 'compact' command

While assembling CBFS images within the RW slots on Chrome OS
    machines the current approach is to 'cbfstool copy' from the
    RO CBFS to each RW CBFS. Additional fixups are required such
    as removing unneeded files from the RW CBFS (e.g. verstage)
    as well as removing and adding back files with the proper
    arguments (FSP relocation as well as romstage XIP relocation).
    This ends up leaving holes in the RW CBFS. To speed up RW
    CBFS slot hashing it's beneficial to pack all non-empty files
    together at the beginning of the CBFS. Therefore, provide
    the 'compact' command which bubbles all the empty entries to
    the end of the CBFS.
