Issue:
tekton controller fails on OpenShift 4.x
when trying to create a `PipelineRun` on OpenShift 4.x we get this error...

```
Failed to create pipeline run: pipelineruns.tekton.dev \"verify-vcszn\" is forbidden: cannot set blockOwnerDeletion if an ownerReference refers to a resource you can't set finalizers on
```

Pull request description:
fix: fix for OpenShift 4.x
avoid setting `blockOwnerDeletion: true` on the `PipelineRun` to avoid failing on OpenShift 4.x
