Alberto Donizetti fcee1e3739 time: vendor tzdata-2017b and update test
This change updates the vendored tzdata database to version 2017b
(released 2017-03-20).

The TestFirstZone test (which always uses the vendored database) is
updated to make it work with the new timezones database. (The Tokelau
abbreviation was changed from 'TKT' to the numeric abbreviation in
tzdata-2017a)

Fixes #19376
