cbfstool: rename checksum to attributes_offset

So far it's still unused, but its purpose will change:
    It will become an offset to another structure that contains additional file
    attributes.

This change is compatible because the binary format doesn't change and so far
    the field was always set to 0, which can serve nicely as 'unused' field.
