Make a few cleanups:
- Remove python 2.7 stanza from setup.py
- Add requires on python >= 3.6 to setup.cfg so that pypi and pip
know about the requirement
- Remove obsolete sections from setup.cfg:
* Wheel is not needed for python 3 only repo
- Update classifiers
- Update requirements, no need for python_version anymore

The scripts run by os-refresh-config generally expect to be running
only once. This will ensure that. Because we use /var/run, this also
now assumes that os-refresh-config is run by root. Otherwise one must
pass in a different --lockfile path.
