Subject: [PATCH] Always generate Python Metadata when WRAP_PYTHON is active

Python Metadata in accordance with PEP 314 is not only used by wheels
(PEP 427/PEP 491), but can also used for `python setup.py
install_egg_info`.

The latter can be used to make a system wide VTK installation available
for other python packages (e.g. installed via pip) which require VTK.
Without the metadata, pip will not find it and always try to download the
wheel.
