HaikuDepot: Show packages that don't have a repository.

- If a package was installed, but didn't have a corresponding remote
  repository package, it would have been missed in the list. Detect these
  and create a special local depot object to house them, so they also make
  their way into the visible package list.

Thanks to diver for reporting the discrepancy.
