Subject: [PATCH] rootless: call dockerd-rootless-setuptool.sh for
 $CHANNEL=nightly

`dockerd-rootless-setuptool.sh` is the new standard way to set up the systemd unit file.
https://github.com/moby/moby/blob/master/contrib/dockerd-rootless-setuptool.sh

The usage of `rootless-install.sh` stays same.
