Switch to python-buster for manylinux wheel (mypy -> typed_ast) support?

[jbooth-mastery]

The choice to use alpine in the build image makes using mypy somewhere between difficult to impossible.

$ docker run --rm -it python:3.8.0-alpine3.10 pip install mypy

Would you consider a switch to the standard python image?
