[ Upstream commitb000def2e0] The test_overhead prog_test included an fmod_ret program that attached to __set_task_comm() in the kernel. However, this function was never listed as allowed for return modification, so this only worked because of the verifier skipping tests when a trampoline already existed for the attach point. Now that the verifier checks have been fixed, remove fmod_ret from the test so it works again.
