Backport upstream fixes for Python 3.12

These are test-only (and thus build-only) except for a
different fallback value for `setuptools.__version__`.

Fixes: RHBZ#2222249

+#   Set a valid dummy value if that's not the case.

+Subject: [PATCH] tests: Add extraction_filter for tarfile
+
+Python 3.12, and earlier via security backports now issue an
+DeprecationWarning when calling tarfile.extractall without an extraction
+filter set. Since the only place we've called extractall is literally
+right after we've created the archive, use a fully trusted filter. This
+can be replaced with a filter argument to extractall in future.

+Subject: [PATCH 1/3] Adequate venv fixtures to the latest change in virtualenv
+
+Since version v20.23.0, `virtualenv` will no longer include `wheel` and
+`setuptools` in the created folders.
+
+Some tests in the setuptools test suite assume that these packages are
+always present. So we need to adequate these tests.
