The only templates Ubuntu needs are the Ubuntu ones, not the junk that is there. It looks like some dev sometime ago had pulled few packages from those distros, but forgot the templates. Just delete them.
You can also see such stuff everywhere, for example, in /etc/grub.d/05_debian_theme. There also it mentions Tanglu 3 times, meaning the file might have been copied from Tanglu. They are simply harmless stuff, though.
