hjfs: update mtime and qid.vers for directory on rename

Browse source 
when wstating a file, its directory should be updated to
reflect this change.

here is what the manpage states:

> The mtime field reflects the time of the last change of content
> (except when later changed by wstat). For a directory it is the
> time of the most recent remove, create, or wstat of a file in the
> directory.
