controller/vmagent: properly assign OwnerReference to Role and RB

Previously, operator assigned VMAgent as Owner for Role and Rolebindg at VMAgent.
But the problem is, that at single-namespace mode operator cannot access CRD and assing proper Owner.
It led to empty OwnerRefence and created role/rolebinding could be deleted by ARGOCD with enabled pruning.

 This commit properly assign OwnerReference to VMAgent CR object not cluster CRD.
