[PATCH bpf-next] selftests/bpf: Test sys_connect BPF hooks with TFO

TCP Fast Open is triggered by sys_sendmsg with MSG_FASTOPEN flag for SOCK_STREAM socket. Even though it's sys_sendmsg, it eventually calls __inet_stream_connect the same way sys_connect does for TCP. __inet_stream_connect, in turn, already has BPF hooks for sys_connect. That means TFO is already
