Description

Whenever you don't set a runmode in the yaml file (or setting runmode: auto) suricata will correctly start runmode unix socket in single mode, but it will then start a single run of a pcap (via RunModeDispatch call, runmode-unix-socket.c:391) using the default runmode for pcap-file, which is autofp.
This will potentially lead to a race condition where a detection thread will hang waiting for another packet while every other thread will shut down.
Furthermore, the behavior is inconsistent with the declaration of --list-runmodes.

Possible fixes:
- use ConfSetFinal in RunModeUnixSocketSingle before registering the background task in order to force the runmode to be set to single
- change function RunModeDispatch in order to add a parameter "run_via_unix_socket"
- add a check in RunModeDispatch, checking the value of RunModeUnixSocketIsActive before actually choosing the runmode (and in case forcing it to single mode)

AFAICS the goal is to run as 'autofp' in unix socket mode.
