[libcxx] Remove localization tests for Russian month names

[Hahnfeld]

Summary

Commit f49839299a085505eb673544744b61d2d9cdd1db in glibc-2.14 changed the locales to the currently required format. However, they were again changed in commit 55bdd2866f23b28422d969060b3518909a12b100 which has been released in 2.17.

That leads to the current situation where Debian and e.g. CentOS 6 have the pre-2.14 locales, for example Ubuntu 14.04 has pre-2.17 and CentOS 7 on the other hand has the newest locales in glibc-2.17.

It seems like we are not losing test coverage with these removals. And they have caused us a ton of pain.

I agree lets just get rid of them!

LGTM.
