neotest: Don't rely on globbing to build $PYTHONPATH

Globbing can be unreliable after incremental profile update and rebuild because
buildout does not remove old eggs. Also it is much more clean to be precise.

-> Use [python-interpreter] to build bin/python with sys.path to wendelin.core
and other needed eggs.
