In order to add a version of bpf_prog_run_array which accesses the
bpf_prog->aux member, we need bpf_prog to be more than a forward
declaration inside bpf.h.
Given that filter.h already includes bpf.h, this merely reorders
the type declarations for filter.h users. bpf.h users now have access to
bpf_prog internals.
