Explicitly check if NETFILTER_BPF_LINK is enabled, else configs
that have NETFILTER=y but CONFIG_INET=n fail to link:
> kernel/bpf/syscall.o: undefined reference to `netfilter_prog_ops'
> kernel/bpf/verifier.o: undefined reference to `netfilter_verifier_ops'
Fixes: fd9c663b9a
("bpf: minimal support for programs hooked into netfilter framework")
