Geliang Tang April 16, 2024, 10:13 a.m. UTC 
From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses public helper make_sockaddr() exported in network_helpers.h
instead of open-coding in bind_sock() in test_sock.c. This can avoid
duplicate code.

Signed-off-by: Geliang Tang <tanggeliang@kylinos.cn>
