The benchmark code and the test_overhead prog_test included fmod_ret
programs that attached to various functions in the kernel. However, these
functions were 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 affected tests so they all work again.
