Add new locales for beta and release builds (batch 9 and 10) (#270)

This is for issue #270.
The "az" and "ff" locales are blacklisted, I raised bug [1074695](https://bugzilla.mozilla.org/show_bug.cgi?id=1074695) for tracking "az", for "ff" we already have bug [1050253](https://bugzilla.mozilla.org/show_bug.cgi?id=1050253).
