cbfstool: unify actual file creation

After the preparation in earlier commits, it is now possible to handle the
    more general case of position independent files using the special code path
    for fixed location files.

This leads to a single place where non-empty cbfs file headers are actually
    written into the image, allowing us to move it up the chain more easily.
