This is actually easier than I first thought. All we need to do is move the
Python loaders to separate binary packages and update dependents which ship
Python support to Depends on the appropriate loader package.
This is an important fix so that we can provide images which only have Python
3 support. See the attached patch. For a list of packages which will need
updated Depends, see
https://bugs.launchpad.net/ubuntu/+source/libpeas/+bug/1440504/comments/6
and
