package/python-setuptools: add missing dependency on host-python-wheel

While migrating to pep517 build backend the host-python-wheel
dependency has been added to host-python-setuptools but
not to python-setuptools. Note that host-python-wheel is not really
needed during the build of (target) setuptools, but the setup.py script
checks if the dependency is present in the host directory.

To make everything consistent, add host-python-wheel as a build
dependency, and BR2_PACKAGE_PYTHON_WHEEL as a runtime dependency.
