Fix locale path

Pretty sure that fixes the locale path problem.

To test:

1. run the tests
2. make sure there is no kitsune/locale/ directory
3. do `./manage.py shell` then:

```
(kitsune) (locale-path-fix=4ec53) saturn ~/mozilla/kitsune> ./manage.py shell
Python 2.7.5 (default, May 29 2013, 22:31:19) 
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> from django.conf import settings
>>> settings.LOCALE_PATHS
('/home/willkg/mozilla/kitsune/locale',)
```

That should show up in the right place.
