[PATCH bpf-next 03/14] selftests/bpf: Use connect_to_addr in cls_redirect

[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 prog_tests/cls_redirect.c. This can avoid duplicate code.
