  Issue #9065: no longer use "root" as the default for the
  uname and gname field.

  If tarfile creates a new archive and adds a file with a
  uid/gid that doesn't have a corresponding name on the
  system (e.g. because the user/group account was deleted) it
  uses the empty string in the uname/gname field now instead
  of "root". Using "root" as the default was a bad idea
  because on extraction the uname/gname fields are supposed
  to override the uid/gid fields. So, all archive members
  with nameless uids/gids belonged to the root user after
  extraction.
