Add regression test coverage for non-default timezone abbreviation sets.

Browse Source 
After further reflection about the mess cleaned up in commit 39b691f25,
I decided the main bit of test coverage that was still missing was to
check that the non-default abbreviation-set files we supply are usable.
Add that.

Back-patch to supported branches, just because it seems like a good
idea to keep this all in sync.

@ -34,6 +34,11 @@ in the same commit. Usually, if a known abbreviation has changed meaning,
the appropriate fix is to make it refer to a long-form zone name instead
of a fixed GMT offset.
The core regression test suite does some simple validation of the zone
data and abbreviations data (notably by checking that the pg_timezone_names
and pg_timezone_abbrevs views don't throw errors). It's worth running it
as a cross-check on proposed updates.
When there has been a new release of Windows (probably including Service
Packs), the list of matching timezones need to be updated. Run the
