python-gpiozero: migrate to setup.cfg

setup.cfg seems to be mandatory since (at least) setuptools 67.8.0
otherwise gpiozero dependencies are not properly detected

File "/builds/buildroot.org/buildroot/test-output/TestPythonPy3Gpiozero/host/lib/python3.11/site-packages/pkg_resources/__init__.py",
line 868, in _resolve_dist
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'colorzero' distribution was not found and is required by the application

See:
http://lists.busybox.net/pipermail/buildroot/2023-June/669207.html

Fixes:
https://gitlab.com/buildroot.org/buildroot/-/jobs/4505977906
