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.
