selftests/bpf: Isolate fmod_ret hooks by pid
modify_return's fmod_ret programs can override bpf_modify_return_test()'s
return value, which conflicts with get_func_ip_test when selftests run in
parallel.
Store current tgid in BSS and make modify_return hooks act only for that
tgid. For other tasks, fentry/fexit become no-ops and fmod_ret returns the
original ret.
Drop the serial-only restriction and remove the TODO comment.
Tested:
sudo ./test_progs -t modify_return
sudo ./test_progs -t get_func_ip_test
sudo ./test_progs -j$(nproc) -t modify_return
sudo ./test_progs -j$(nproc) -t get_func_ip_test
