[PATCH bpf-next 14/14] selftests/bpf: Use connect_to_addr in test_tcp_check_syncookie

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

This patch uses public helper connect_to_addr() exported in
network_helpers.h instead of the local defined function connect_to_server()
in test_tcp_check_syncookie_user.c. This can avoid duplicate code.
