Adding selftest that puts kprobe.multi on bpf_fentry_test1 that calls bpf_kfunc_common_test kfunc which has 3 perf event kprobes and 1 kprobe.multi attached. Because fprobe (kprobe.multi attach layear) does not have strict recursion check the kprobe's bpf_prog_active check is hit for test2-5. Disabling this test for arm64, because there's no fprobe support yet.
