smoke-tests: guess the lighthouse container IP better (#1347)

Browse Source 
Currently we just assume you are using the default Docker bridge network
config of `172.17.0.0/24`. This change works to try to detect if you are
using a different config, but still only works if you are using a `/24`
and aren't running any other containers. A future PR could make this
better by launching the lighthouse container first and then fetching
what the IP address is before continuing with the configuration.
