closes bpo-35171: Fix test_TimeRE_recreation_timezone failure on some systems. (GH-10347)

The test depended on '/usr/share/zoneinfo/posixrules' or equivalent
because it set TZ without explicit DST transition rules. At least
on OpenSUSE Tumbleweed that file is linked to '/etc/localtime',
making the test fail with certain local timezones,
such as 'Europe/Moscow' which doesn't have DST transitions since 2011.
(cherry picked from commit f1b9ad3d38c11676b45edcbf2369239bae436e56)
