- Mk/Uses: remove the default deprecation date.
Obviously the world did not manage to get rid of Python 2.7 by 2020-12-31, so remove that target and just advise users to move on to Python 3.
- games/renpy: remove past expiration date
- lang/tauthon: remove past expiration date.
Keep this port deprecated, as it is a Python 2.7+3.X clone. Nothing in the tree currently uses this port, but www/palemoon will if it is ever resurrected.

- cleanup: remove transitive py27 deprecation (www/chromium)
