This function comes up not a first time, I guess it makes sense to
finally make it a public API. We should also try to minimize number of
internal APIs used by bpftool.
So if no one objects to expose it, should we call it a bit more
precisely and according to libbpf naming guidelines:
libbpf_load_kernel_btf? libbpf_find_kernel_btf is acceptable, but it
does more than just finding, thus "load". It should also probably live
in btf.c+btf.h? WDYT?
