Subject: distutils-r1.eclass: Fix setuptools without setup.py
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Invoke pyproject2setuppy directly instead of writing the setup.py
wrapper.  This is necessary to correctly support setuptools via
pyproject.toml without setup.py.  Writing setup.py confuses
pyproject2setuppy into running the setup.py code path instead of
the correct non-setup.py path.
