package/dt-utils: bump to version 2023.08.0

COPYING is now a symlink pointing to LICENSES/GPL-2.0-only.txt. More
license files were added and all source code files were updated with
proper license being used. See [1-4].

List all licenses used in runtime by produced binary (and omit
GPL-3.0-or-later for check-news.sh script).
