pgsql: Sync our copy of the timezone library with IANA release tzcode20 - Mailing list pgsql-committers

Sync our copy of the timezone library with IANA release tzcode2020d.

There's no functional change at all here, but I'm curious to see
whether this change successfully shuts up Coverity's warning about
a useless strcmp(), which appeared with the previous update.
