MT#57855 venv deployments: use venv instead of virtualenv

When invoking `virtualenv --python=python3 virtualenv` to deploy the
virtual environment, installing the python-debian wheel, and then
re-executing `virtualenv --python=python3 virtualenv` once again, we
might end up without the virtualenv/lib/python*/site-packages/debian
directory, resulting in:

| Traceback (most recent call last):
|   File "<string>", line 1, in <module>
| ModuleNotFoundError: No module named 'debian'

This is a bug in setuptools >=51.3.3-1, see
https://bugs.debian.org/1041091 for the details, so currently affecting
all systems with Debian/bookworm.

By excluding installation of setuptools (via --no-setuptools), we would
be able to work around this bootstrapping problem itself, though then
installation of django-jsonify (which we depend on) fails with:

| ModuleNotFoundError: No module named 'setuptools'

Let's take this as a chance to switch from virtualenv to the more
lightweight venv, quoting https://docs.python.org/3/library/venv.html:

| Changed in version 3.5: The use of venv is now recommended for creating virtual environments.
