Unbreak "setup.py install"
Unbreak "setup.py install"

python setup.py install fails with:
error: can't copy 'sahara_dashboard/content/data_processing/locale':
doesn't exist or not a regular file

The symbolic link does not work with setuptools, this needs to be
handled differently. Remove for now to get requirements gate working
again as this blocks *all* changes for the requirements repository.
