[PATCH bpf-next v2 12/14] selftests/bpf: Use connect_to_fd in sockopt_inherit

[Geliang Tang]

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

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