Allow chained network namespace containers

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
