[PATCH bpf-next 08/14] selftests/bpf: Use connect_to_addr in test_sock_addr

[Geliang Tang]

From: Geliang Tang <tanggeli...@kylinos.cn>

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