networking: lookup child IP in networks
if a CNI network is added to the container, use the IP address in that network instead of hard-coding the slirp4netns default. commit 5e65f0ba30f3fca73f8c207825632afef08378c1 introduced this regression. Closes: https://github.com/containers/podman/issues/9065 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
