The current ifdefry for code shared by the BPF and ctnetlink side looks
ugly. As per Pablo's request, simplify this by unconditionally compiling
in the code. This can be revisited when the shared code between the two
grows further.

Pablo, presumably this needs your ack before it can be applied, as it
is marked Needs Ack in patchwork.
