pcap_io: introduce init_once helper that is called with priviledges
When using netsniff-ng with dropping priviledges, we have to introduce another pcap helper function that is called once before we drop the priviledges. In this function we have to invoke the disc I/O scheduler policy, because it needs priviledges. Otherwise netsniff-ng will fail with "Failed to set io prio for pid" on startup, since we're not root anymore.
