Fix test failures due to previous change of not setting TZ by default.

Fix by explicitly setting timezone for a few more tests that need it.
(We avoid setting TZ everywhere by default as this breaks some tests
on windows).

Also add fix of two other windows failures due to non-portable
suppressions, thanks to Alex Budovski.

mysql-test/mysql-test-run.pl:
  Don't let --timezone option from one test stray into the next test
  (mostly to make results more deterministic rather than depend on
  whatever test happens to run just before).
mysql-test/suite/maria/r/maria-recover.result:
  Fix suppression pattern to also work with Windows \ path separator.
mysql-test/suite/maria/t/maria-recover.test:
  Fix suppression pattern to also work with Windows \ path separator.
mysql-test/suite/parts/inc/partition_timestamp.inc:
  Set timezone explicitly for test that needs it.
