b5fd346589 Move jhash out of headers/linux into include/ 
It is a bit strange we have this header file in this repo, but
it likely be very useful later.

d5031bfc92 headers/linux: add netlink.h from kernel source v5.11-rc7 
This is included by linux/if_link.h.  Thus, we need it here if the
distro doesn't provide this include file.

23ae3dcf45 Remove bpf_helper_defs.h as this comes via libbpf 
The bpf_helper_defs.h is used by (ibbpf provided) bpf/bpf_helpers.h.
Thus, it doesn't belong under headers/ directory.

Remove file: headers/bpf/bpf_helper_defs.h

Fixes: f0fce8f62b ("Update kernel headers and libbpf version")

9ea235637e Add compiler.h to define some common compiler directives 
This is taken from the Cilium project:
 https://github.com/cilium/cilium/blob/master/bpf/include/bpf/compiler.h

The use-case was adding READ_ONCE and WRITE_ONCE, but via re-using
the Cilium version we get a lot more useful compiler annotations.
