v2: correct and test controller RBAC

Prior to this commit the declared permissions for the RedpandaReconciler had
become out of date. This went unnoticed due to tests utilizing admin
permissions or the inflated permissions required for executing `rpk debug
bundle`.

This commit corrects the permission declaration of the RedpandaReconciler,
updates its tests to use the ClusterRole and Role generated by controller-gen,
and adds a test to statically assert the correctness of the permissions.
