python: Use setuptools instead of distutils.

On Python 3.12, distutils will be removed and it's currently (3.10+)
deprecated (see PEP 632).

Since the suggested and simplest replacement is setuptools, this commit
replaces distutils to use setuptools instead.

setuptools < 59.0 doesn't have setuptools.errors and so, in this case,
distutils.errors is still used.
