Previously, this check only worked if no host was specified and was
hard coded to check for "/var/run/docker.sock"
This change generalizes that check and captures any specified socket
and waits for it to be created.
Caveat: This will only check the first socket specified, but it is an
improvement over none at all.
Fixes#185160
