modify_script uses a variable declared outside of the function

[alanking]

This seems to work since the univmss_script variable is declared in the function containing this function, but we should really use the script parameter to be correct: https://github.com/irods/irods_testing_environment/blob/a61cd7a6afc776c9fe82ecfce177ca85d5b6f631/irods_testing_environment/irods_config.py#L279-L283

that's weird. it's always been this way?

It probably became this way when adding parallel-ism to the test suite. Like I said, it seems to work, but that's just coincidental here. Also, the run_tests.py script also seems to do this work, so it really doesn't matter that much in the end.
