I think you could do this with:

  size_t len;
  if (strip_suffix(patch->new_name, GITATTRIBUTES_FILE, &len) &&
      len > 0 && is_dir_sep(patch->new_name[len-1]))
          flush_attributes = 1;

Not sure if that is better or worse. It avoids the extra memory
boilerplate, but the logic is a slightly more subtle.
