[Bug 31785] Add more languages and locales to the core tests

https://bugs.winehq.org/show_bug.cgi?id=31785

--- Comment #3 from François Gouget  ---
We now have two Windows Ultimate VMs: Vista and Windows 7. One is running the
tests in a right-to-left locale (Hebrew) and the other in a double-byte
language (Japanese). So we have some coverage.

It does seem though that Chinese and particularly Korean get different failures
from Japanese so an extra test environment may be useful. Also one VM was
recently switched from Arabic to Hebrew as the latter seemed to have more
failures but it's possible failures will now accumulate in Arabic.
