This will be useful in the upcoming listdir utility (in the next commit) to get the file type which is obtained in the get_dir_entries syscall, so it's not changed later by the fstatat syscall. This will ensure that we get the raw file type value as it's represented by directory entries from the get_dir_entries syscall.
