Fix invocation with Python 3.9 (#1798929)

Backported from Fedora 31:
https://src.fedoraproject.org/rpms/python-tox/c/aa466cd2d67b5ca7e5f4f58d0fbc704b38c97d94?branch=f31

Added 3.10 and 3.11 as well.

With this tox.ini:

    [tox]
    skipsdist = True
    [testenv]
    commands = python -c 'import sys; print(sys.version)'

Before:

    $ tox -e py39
    ...
    3.6.8 (default, Aug 24 2020, 17:57:11)
    ...
      py39: commands succeeded
      congratulations :)

After:

    $ tox -e py39
    ...
    3.9.1 (default, Jan 18 2021, 16:14:01)
    ...
      py39: commands succeeded
      congratulations :)

The Python 3.10+ addition remains untested, as I have no Python 3.10+ build for EL 8 available.
