for workload clusters cluster-vip Kustomization has wrong namespace

While looking at !2062 (merged) I realized that I had in my workload cluster a cluster-vip Service in sylva-system that just shouldn't be there (we're supposed to only have a cluster-vip Service in kube-system defined by the cluster-vip unit.

The reason is:

$ kubectl get ks -n my-capo-wc cluster-vip -o yaml | yq .spec.targetNamespace
sylva-system
