Make bpf_attach_tracepoint() available as soon as possible
The "sys.init.perf_lsm_hooks" is set on TestPerEventSelinux and it
is before early-init, but it need trigger by queue_property_triggers
and it is after late-init (zygote start on late-init).
The property is ready on load_bpf_programs, make sure
bpf_attach_tracepoint() is available on zygote start.
