test: Python test fixes: GSF + EDM4hep (#4088)

This fixes a few small issues with the GSF debugger (shebangs) and using the python interpreter that runs pytest (otherwise modules might not be available).

It also forces DD4hep to write EDM4hep for the EDM4hep ddsim run, which gives a better error message if DD4hep was built without EDM4hep.
