[3.15] gh-150046: Fix `test_add_python_opts` to ignore `PYTHON*` env vars (GH-150089) (#150561)

gh-150046: Fix `test_add_python_opts` to ignore `PYTHON*` env vars (GH-150089)

Avoid the runtime environment from affecting the tests' behaviours,
which notably checks the warning filters which can be controlled by
various PYTHON environment variables.
(cherry picked from commit ef2246f788832a64ba7c5215c8e72f8e539e59b4)
