  odb: only provide the empty tree
  
  Only provide the empty tree internally, which matches git's behavior.
  If we provide the empty blob then any users trying to write it with
  libgit2 would omit it from actually landing in the odb, which appear
  to git proper as a broken repository (missing that object).
