[PATCH bpf-next v3 1/4] selftests/bpf: Use log_err in network_helpers

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

The helpers ASSERT_OK/GE/OK_PTR should avoid using in public functions.
This patch uses log_err() to replace them in network_helpers.c.

And drop '#include "test_progs.h"' in it, include <pthread.h> and
<sys/param.h> instead.
