Summary

fixed a return curr_symbol() for Russian in the libcxx/test/support/locale_helpers.h for AIX

[Mordante]

Thanks for the fix! I see several other monetary tests using the Russian locale that fail for AIX.
I'm not sure whether they fail on the Russian or another locale. So I'd like to see the CI green before approving.

The CI is green so LGTM! Please wait a few days before landing so the AIX maintainers can have a look too.

LGTM, thanks!
