[ruby/date] Add more timezone abbreviations
This gets the time zone abbreviations from
https://www.timeanddate.com/time/zones/, and adds unambiguous time
zones not already present in zonetab.list. See bin/update-abbr
for the program used.
This regenerates zonetab.h using prereq.mk (requires gperf).
Only one test line is added, just to make sure a new time zone
abbreviation is picked up.
Fixes Ruby Bug 16286
