silverwind ae9ce10f71 fix: register docker-init as subreaper in the dind images (#1241)
The dind images run `s6-svscan` as PID 1, so the `docker-init` that the upstream entrypoint puts in front of `dockerd` cannot reap and warns on every start. `TINI_SUBREAPER` makes it a subreaper for the daemon's subtree, which is what tini recommends when it is not PID 1.

The warning was cosmetic. Orphaned `containerd-shim` processes re-parented to `s6-svscan`, which reaps them just as well, so no zombies accumulated. With this change they re-parent to `docker-init` instead, and the warning is gone.
