templates: Filter C.UTF-8 locale for translation

In addition to C locale there is also C.UTF-8 locale now. Filter that as
well, by using ${grub_lang}, which contains a stripped value.
This fixes the following message and resulting boot failure:

    error: file `/boot/grub/locale/C.gmo' not found.
