dev-python/pure-protobuf: patch exclude variable in setup.py

we used the python_foreach_impl function wrong

python_install is already run with python_foreach_impl,
thus the function should not be used inside python_install

for this there is python_install_all, but this is run after
python_foreach_impl python_install so we again get the
'${P} installs tests' error. Instead I just patched
a fix, this fix is also already in upstream master
