distutils: fix dependency and lib replacement

As of now, the distutils is deprecated with removal planned for
python 3.12.

The recommended way is to use setuptools which is an enhanced
alternative to distutils maintained by the python packaging authority.

This commit replace with setuptools the distutil import inserted in the
8126ef0c00 commit.

This commit also update the debian control runtime dependency.
