fixed ip addr retrieval for inspect --all case

Hi @karimra
I wonder if you consider this to be a less intrusive approach as opposed to #433 ?
The assumption here is that clab containers can have only one network they are connected to

[karimra]

That was the way it was done before the runtime introduction.

I did it that way first then decided to query the bridges that were created by clab, users can always do a docker network connect someDockerNetwork clab-nodeX making the output random.

But under the assumption that only one docker network is connected, both ways work. The extra step is a docker network listing.

agree, that makes sense to let ppl to mess with container networking afterwards
