1.7.5 replaced py.process.ForkedFunc with multiprocessing, so swap the
python3-py runtime dependency for python3-multiprocessing. The sdist is
now named pytest_forked, the pypi class default, so drop
PYPI_PACKAGE_SDIST.
Backport the pending upstream fix for pytest 9.2, where TestReport
carries a NodeId object in _id that marshal cannot serialize; every
forked test crashed with "ValueError: unmarshallable object". This made
python3-starlette ptests report no results at all; all of them pass
now on qemux86-64.
