Fix standardFinalizers - add missing metav1.FinalizerDeleteDependents

**What this PR does / why we need it**:
It adds [FinalizerDeleteDependents](58167fcfa1/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/types.go (L77)) to [standardFinalizers](58167fcfa1/pkg/api/helper/helpers.go (L222)) otherwise this finalizer is unusable because apiserver will fail validation because it is not fully qualified name - but it is a standard Kubernetes finalizer [used by garbage collector](58167fcfa1/pkg/controller/garbagecollector/garbagecollector.go (L389)) but it can't be set.

It's sibling [FinalizerOrphanDependents](58167fcfa1/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/types.go (L76)) is already [there](58167fcfa1/pkg/api/helper/helpers.go (L224)). I suppose this is a bug because otherwise `FinalizerDeleteDependents` is unusable.

Fixes https://github.com/openshift/origin/pull/14322
Might fix https://github.com/kubernetes/kubernetes/pull/45764

**Not for the reviewer:**
[This same definition is also in staging.](58167fcfa1/staging/src/k8s.io/client-go/pkg/api/helper/helpers.go (L222)) Does it get propagated to staging automatically? Editing the same file twice doesn't seem like the intended option.
