Flakebi 9f8670c206 paperless: Fix build
paperless wasn't building because django-cors-headers didn't
build anymore with the pinned django version.

I tested the paperless service (editd a few documents) and it works
fine, even with django unpinned.

## Usage
# ${paperless}/bin/paperless wraps manage.py
# ${paperless}/share/paperless/setup-env.sh can be sourced from a
# shell script to setup a Paperless environment
# paperless.withConfig is a convenience function to setup a
# configured Paperless instance. (See ./withConfig.nix)
# For WSGI with gunicorn, use a shell script like this:
# let
# pythonEnv = paperless.python.withPackages (ps: paperless.runtimePackages ++ [ ps.gunicorn ]);
# in
# writers.writeBash "run-gunicorn" ''
# source ${paperless}/share/paperless/setup-env.sh
# PYTHONPATH=$paperlessSrc ${pythonEnv}/bin/gunicorn paperless.wsgi
