fix(api): add ownerReference for BDC

[niladrih]

Why is this PR required? What issue does it fix?: LocalPV Device from openebs/dynamic-localpv-provisioner requires addition of ownerReference for the BDC to the PVC. This file is included in the vendor directory for the dynamic-localpv-provisioner repo.

The workflow involved here:

1. Add ownerReference for BDC in https://github.com/openebs/maya/tree/master/pkg/blockdeviceclaim/v1alpha1/build.go
2. Update vendoring directory in openebs/dynamic-localpv-provisioner
3. Add owner reference option in https://github.com/openebs/dynamic-localpv-provisioner/tree/master/cmd/provisioner-localpv/app/helper_blockdevice.go
4. Pass PVC to reference to getBlockDevicePath method
5. blockdeviceclaim/v1alpha1/build.go attaches owner reference.

Ref: Cleanup of stale BDCs in https://github.com/openebs/openebs/issues/3263

What this PR does?:

1. Changes the input signature for WithOwnerReference method to empty interface to be able to get both (v1.PersistentVolumeClaim) and (apis.StoragePoolClaim) as input.
2. Adds reference block to issue ownerReference to PVC.
