OTP-8387 Explicit top directories in archive files are now optional.

          For example, if an archive (app-vsn.ez) just contains an
          app-vsn/ebin/mod.beam file, the file info for the app-vsn and
          app-vsn/ebin directories are faked using the file info from the
          archive file as origin. The virtual direcories can also be
          listed. For short, the top directories are virtual if they does
          not exist.
