Set UID in Brokers backing channels EventPolicies OwnerReference

[creydr]

Currently seeing the following error in the controller logs:

failed to reconcile EventPolicy for Broker broker-iinpthqx: failed to create EventPolicy for Broker broker-iinpthqx-ep-broker-iinpthqx-kne-trigger: EventPolicy.eventing.knative.dev \"broker-iinpthqx-ep-broker-iinpthqx-kne-trigger\" is invalid: metadata.ownerReferences.uid: Invalid value: \"\": uid must not be empty

This PR addresses it and sets the UID in the Owner reference.

Proposed Changes

• 🐛 Set UID in Brokers backing channels EventPolicies OwnerReference
