selftests/bpf: Add selftests for raw syncookie helpers
This commit adds selftests for the new BPF helpers:
bpf_tcp_raw_{gen,check}_syncookie_ipv{4,6}.
xdp_synproxy_kern.c is a BPF program that generates SYN cookies on
allowed TCP ports and sends SYNACKs to clients, accelerating synproxy
iptables module.
xdp_synproxy.c is a userspace control application that allows to
configure the following options in runtime: list of allowed ports, MSS,
window scale, TTL.
A selftest is added to prog_tests that leverages the above programs to
test the functionality of the new helpers.
