recipetool/create_buildsys_python.py: less distutils

'distutils' is deprecated in Python 3.10 with removal in Python 3.12
(~October 2023). Replace 'distutils.command.build_py' with
'setuptools.command.build_py'.

To avoid an AttributeError, we call super().__init__() which provides
the missing 'distribution' attribute. However, for some reason, __init__()
in 'setuptools.command.build_py.build_py' class requires a 'dist' positional
argument which must be a 'Distribution' instance. It is not clear why
'distutils.command.build_py.build_py' class does not require this.

There is still a check which decides to inherit setuptools3 vs distutils3
that will need to be refactored when we add pyproject.toml and setup.cfg
support for more modern PEP 517 packaging.

Once distutils3.bbclass is dropped, any recipe inheriting distutils3
will throw a parsing error. The plan is to move distutils*.bbclasses to
meta-python. However if meta-python is not in bblayers, the parsing
error would still occur.
