bpf: Allow the new syncookie helpers to work with SKBs
This commit allows the new BPF helpers to work in SKB context (in TC
BPF programs): bpf_tcp_raw_{gen,check}_syncookie_ipv{4,6}.
Using these helpers in TC BPF programs is not recommended, because it's
unlikely that the BPF program will provide any substantional speedup
compared to regular SYN cookies or synproxy, after the SKB is already
created.
