cbfstool: Add offset field to cbfstool directory's struct buffer
This allows calls to buffer_delete() to work on a buffer that has been
buffer_seek()ed or the buffer created by a buffer_splice(). The same
information could also be useful for other purposes, such as writing
slices back to a file at the offset they originally occupied.
