selftests/bpf: test MSS value returned with bpf_tcp_gen_syncookie

Browse source

One remaining difference between test_tcp_check_syncookie.sh and
btf_skc_cls_ingress is a small test on the mss value embedded in the
cookie generated with the eBPF helper.

Bring the corresponding test in btf_skc_cls_ingress.
