Kai-Heng Feng 8705a16d48 platform: add a new function nmp_utils_open_sysctl()
A race condition may happen when NetworkManager opens sysfs and udev
renames interface name at the same time. Thomas Haller provides a new
function [1] which can avoid the race condition when opening sysfs.

This patch is a direct copy from [1].
