misc/zoneinfo: install zone1970.tab and other fixes

Install zone1970.tab in addition to zone.tab (like D20646 for base).

The old logic to remove countries from zone.tab doesn't port to
zone1970.tab since some lines might have to be patched more than
once. Replace it with some awk.

Remove LEAPFILE reference that wasn't being set anyway.

Fix plist entry for Etc/UCT, which is (since 2019a) part of
"backward" and not present otherwise.

Make BACKWARD not be the default, since (a) it's not the base system's
default and (b) that stuff is all deprecated.

Update to 2019b

Brazil has canceled DST and will stay on standard time indefinitely.

When there is a do-install target, do not use a post-install target, do
everything at once.  Sometime, rename post-install into a options helper
target.

I did not fix ports that were such a mess that I could not figure out
what they really wanted to do.  I also did not change ports that had
some version of an auto-plist code in post-install, for the same reason.
