Allow chained network namespace containers

Browse Source 
The code currently assumes that the container we delegate network
namespace to will never further delegate to another container, so
when looking up things like /etc/hosts and /etc/resolv.conf we
won't pull the correct files from the chained dependency. The
changes to resolve this are relatively simple - just need to keep
looking until we find a container without NetNsCtr set.

Fixes #4626
