Tests are broken on Windows when using virtualenv

[fohrloop]

Description

The tests ran with tox -e py38 will fail due to problems of creating virtual environments on Windows. This happens with virtualenv and not when using venv (the --use-venv flag). One of the reasons is that pyvenv.cfg is not created. For more info, see comments on this PR.

Expected behavior

Tests will run without problems.

pip version

Commit d08f968

Python version

3.8.5 64-bit

OS

Windows

How to Reproduce

1. Check out a recent version of pip from GitHub (commit d08f968)
2. Run tests with tox -e py38 -- -n auto --exitfirst

Output

Given our Windows 3.8 CI is currently not on fire and no recent complaints from contributors on Windows, I will assume that this is no longer relevant. Of course, there may be issues in odd situations, but new issues can be filed in that case.
