macOS failing on GitHub Actions: test_pythoninfo.GetInfoTests

We should handle the directory issue on GA but as I commented let's create an issue and solve it separately.

FAIL: test_venv (test_pythoninfo.GetInfoTests.test_venv)

In macOS, /var is a symlink to /private/var.

Check pull request #424 first, since it is already open for this issue. Otherwise start with pyperformance/tests/test_pythoninfo.py at test_venv and compare the macOS GitHub Actions failure with the expected values; done means the test passes on macOS without the /var versus /private/var discrepancy.
