Bug 10447: add 'ru' and 'uk' to Zebra indexing language list

This patch add the option to choose 'ru' and 'uk' during install for Zebra.
Should work for a tarball install, and make 'ru' and 'uk' available for using
with koha-create too.

Reran Makefile.pl and made sure the language options show up now.
Patch extends existing language code lists addings nb, ru and uk
where missing.
