www/py-django-solo: Switch to Django 2.2 (current LTS release)
- Also switch to GitHub for a while to update to the latest commit that contain adjustments for newer Django versions and add a patch to fix the build in this state.
- Sort the variables a bit according to the PHB and remove superfluous trailing slash of the Github URL while I'm here.
