PNOR: Fix the delete implementation

- In order to remove the delete object from functional
  image, the delete interface is moved inside the
  version class so that both item_updater and image_manager
  can make use of the same implementation.
- To avoid having two delete objects attached to the same
  HOST version (item_updater and image_manager), we are now
  deleting the image_manager object once the activation
  is complete.

Partially resolves openbmc/openbmc#2490
