contrib/tzdata: correct DST in Jordan and Samoa

Direct commit to stable/13.

The recent tzdata 2021b release includes several controversial changes
under active debate on the tz mailing list.  Pending consensus, and
hopefully a 2021c release reflecting it, only merge the DST changes for
Jordan and Samoa.  This corrects present and future timestamps in those
regions.
