Remove unneeded log keys.

[Harwayne]

Proposed Changes

• Remove unneeded log keys.
  • knative.dev/controller is set by pkg/reconciler just before calling our reconciler, so adding a second one in main is redundant and produced entries with:

    {
      "knative.dev/controller": "controller",
      "knative.dev/controller": "trigger-controller",
    }

  • The reconcile key is already saved as 'knative.dev/key' by pkg/reconciler, so we don't need to add 'key' as well.
