bpfloader: also load from /vendor/etc/bpf/
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).
