These translation sections are not needed anymore, Babel can
generate translation files without them.
Remove babel.cfg as well, this is the default role and not needed
anymore.

We moved to DistUtilsExtra because it promised a more automatic workflow
from setup.py. It doesn't actually deliver though, and it also vomits
warnings during setup.py usage, and also breaks pip integration.
So this is going back to babel. Mostly folks shouldn't need to know
anything about this. We'll need to update the translations import
jobs in Jenkins, and we might need to add a corresponding translations
upload job that runs post-merge.
Translations installation doesn't fully work - but it actually wasn't fully
working before. Getting this part of the project done now though is a
pre-requisite for using tox for multi-python testing (tox starts by
creating an sdist tarball and then installing it into the venv, which
is just 100% broken with DistUtilsExtra)
