[ws-daemon] Re-establish IWS on restart

[csweichel]

fixes #5079

ws-daemon provides an in-workspace service (IWS) to workspacekit. We use this IWS to establish the UID/GID mapping, mount proc and sysfs, prepare the rootfs and unmount it all on shutdown. If the IWS is not available, the workspace does not function well. Prior to this change, ws-daemon would not re-establish the IWS for already running workspaces due to a missing call in the lifecycle hooks.

How to test

1. Start a workspace
2. Restart the ws-daemon on the node where the workspace is running
3. Run docker run --rm -it alpine:latest in the workspace. The container should just run and not complain about procfs.
