Add --without-python to resource group run_tests
Add --without-python to resource group run_tests

Seems resource group run_tests task didn't configure with Python
before and seems image doesn't have PYTHON, as changing the configure
default failed the job. Hence, explicitely adding --without-python to
retain old functionality with changed default.
