bpf: Move endianness BPF helpers out of bpf_util.h
We do not want to include things like stdio.h and friends into eBPF program builds. bpf_util.h is for host compiled programs, so eBPF C-code helpers don't really belong there. Add a new bpf_endian.h as a quick fix for this for now. Signed-off-by: David S. Miller <davem@davemloft.net>
