test/e2e: unshare --rootless-netns cleanup slirp4netns

Browse Source 
podman unshare --rootless-netns leaks the namespace and slirp4netns by
design as there is no safe way to remove it without any races.

To trigger a cleanup we can spin up a container and it will
automaticallt teardown the netns for us.
