Add an explicit check for deprecated pkg_resources namespace packages
to 60python-site. The eclass handled the most common
case of installing them via the deprecated `namespace_packages`
setuptools key, but it does not handle packages that worked around
the deprecation warning by installing the file manually, or ebuilds
that did strip `namespace_packages` to silence the setuptools
deprecation warning.
