In python3.11 getpath.py calculates zip path with default prefix in a venv which breaks venv created fron non-installed python

Bug report

In python3.11, getpath.py calculates zip path with default prefix in a venv. Before python3.11, the zip path is calculated with prefix instead if in a venv.

This change breaks a venv created from a non-installed python with a stdlib zip file.

Sorry, seems the newly added test case will fail with shared enabled python builds. I'm preparing a fix here.

Thanks for the quick fix!
