[issue20220] test_datetime, test_tarfile, test_strptime time zone failures

I added test_strptime to the title due to Issue 22795, but Antoine’s trick doesn’t seem to help reproduce it. In this run <http://buildbot.python.org/all/builders/s390x%20RHEL%203.4/builds/173/steps/test/logs/stdio> all three failed:

[158/390] test_imaplib

Here is a patch that adds DST rules. I think it should work around the problem at least for test_datetime and test_tarfile.
