BMC: Fix the delete implementation.

- Implement delete interface inside version class
  so that both item_updater and image_manager can
  share the same interface. This meant removing the
  delete interface from inside the activation class.
- The delete is created as a separate object inside
  version, only if the image is non-functional.
  This helps remove the delete interface from a
  running BMC/HOST image.
- As part of the activation process, the version from
  inside the image_manager is deleted and so is the
  version's tarfile from the image upload dir.

Partially resolves openbmc/openbmc#2490
