tar4ibd does not check for doublewrite buffer pages

The xtrabackup binary has the following code to skip checksum verification for doublewrite buffer pages:

"
#ifndef INNODB_VERSION_SHORT
   if (buf_page_is_corrupted(page + chunk_offset))
#else
   if (buf_page_is_corrupted(page + chunk_offset, zip_size))
#endif
   {
    if (
#ifdef XTRADB_BASED
        trx_sys_sys_space(node->space->id)
#else
        node->space->id == 0
#endif
        && ((offset + (IB_INT64)chunk_offset) >> page_size_shift)
           >= FSP_EXTENT_SIZE
        && ((offset + (IB_INT64)chunk_offset) >> page_size_shift)
           < FSP_EXTENT_SIZE * 3) {
     /* double write buffer may have old data in the end
        or it may contain the other format page like COMPRESSED.
         So, we can pass the check of double write buffer.*/
     ut_a(page_size == UNIV_PAGE_SIZE);
     fprintf(stderr, "[%02u] xtrabackup: "
      "Page %lu seems double write "
      "buffer. passing the check.\n",
      thread_n,
      (ulint)((offset +
        (IB_INT64)chunk_offset) >>
       page_size_shift));
"

However, tar4ibd does not have this check, so in case of checksum mismatch for such pages, tar4ibd would fail whereas xtrabackup would succeed with a warning.
