test/pytest_suite: auto-create .venv via python3+pip when uv is unavailable

runtests.sh already bootstrapped the virtualenv with `uv sync` when uv
was present, but exited with an error when it was not.  Fall back to
`python3 -m venv .venv && .venv/bin/pip install -e .` so the suite is
self-bootstrapping on systems that have only a stock Python 3 install.
