Nope, sorry, I don't think I want to do this for libbpf. This will
just make Github synchronization trickier, and I don't really see a
point.

I'm totally fine with libperf making a copy of these helpers, though
(this is not complicated or tricky code). I also don't think it will
change much, so there is little risk of any sort of divergence.
