When collecting reports, the runtime re-detection was passing RuntimeAuto
instead of the user's configured preference. This caused podman to switch
back to docker on systems like CoreOS where podman provides a docker-
compatible socket at /var/run/docker.sock.
Now the current runtime (set at init from user's --docker-runtime flag)
is passed as the preference, preventing spurious runtime switching.
