Allow vendors to use bpf programs, but limit to tracepoints for now (other types of programs, for instance skfilter, aren't safe to expose, because the kernel gives us limited ways to control which resources can have BPF programs attached, and some shared resources only support a single BPF program at an attach point). Bug: 140330870 Bug: 162057235 Test: install bpf program to /vendor/etc/bpf/ and use it. Test: atest libbpf_load_test Change-Id: I6c876fe52739c38db73689ffd784167e7d35d58a
