This helper is needed in multiple tests. Instead of copying it over and over, better to deduplicate this helper to test_progs.c. test_progs.c is chosen over testing_helpers.c because of this helper's use of CHECK / ASSERT_*, and the CHECK was modified to use ASSERT_* so it does not rely on a duration variable.
