Fix local run mode to eventing-controller

[themue]

Description

Changes in #11404 showed that local running of the eventing controller doesn't work anymore. Beside setting environment variables the controller had to react at runtime.

Expected result

When the eventing-controller runs on the dev machine, the event-publisher-proxies ownerref should be either ignored or set to a junk value, so that the functionality doesn't break.

Actual result

Error log tells that deployment cannot be found.

Steps to reproduce

$ k port-forward -n kyma-system svc/eventing-nats 4222
$ make run

The issue is from here where the eventing-controller tries to "look itself up" in the cluster.

One solution could be to move out the setAsOwnerReference out into a separate file, and use build tags (e.g. debug and !debug) to replace the implementation with a dummy one. This way a local make target with the right tag could be used to run the controller in the IDE.
