pgsql: Update time zone data files to tzdata release 2012e.

Update time zone data files to tzdata release 2012e.

DST law changes in Morocco; Tokelau has relocated to the other side of
the International Date Line; and apparently Olson had Tokelau's GMT
offset wrong by an hour even before that.

There are also a large number of non-significant changes in this update.
Upstream took the opportunity to remove trailing whitespace, and the
SCCS-style version numbers on the individual files are gone too.
