cbfstool: pass cbfs_file header into "compress" functions

These functions can do all kinds of things, such as converting an ELF
    image into SELF, or (in the future) compress or checksum entire files.
    This may require changing or adding fields to the header, so they
    need to have access to it.

The header_size parameter that was provided (but never used) is
    equivalent to cbfs_file's offset field.
