selftests: Remove fmod_ret from test_overhead

Browse Source 
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.

Fixes: 4eaf0b5c5e ("selftest/bpf: Fmod_ret prog and implement test_overhead as part of bench")
