Comment 10 for bug 1558819

A deeper look at 'ps -ef' shows that most (if not all) processes spawned by other agents (l3 agent, ovs agent...) are daemonized (keepalived, ip monitor... have their PPID == 1), so that explains why get_root_helper_child_pid doesn't see them and why it didn't reproduce sooner. I'm fine with modifying the function as Assaf proposed.
