When reloading rules using `suricatasc`, the UNIX manager can hang. This reproduces on a 5.0.2 system with various Napatech NICs.
This is where the hang occurs: https://github.com/OISF/suricata/blob/master/src/detect-engine.c#L1850:L1861
The issue occurs because the Napatech packet source isn't invoking `TmThreadsCaptureHandleTimeout` when there are no packets to process (that is, when "get next packet" results in a timeout).
