NAS_Templates: fix ts_NAS_GUTI

The template ts_NAS_GUTI permutates the MCC/MNC digits in a weird way, which seems to map to a format that is not used anywhere else. Also the template is not used anywhere yet.

Let's not permutate the MCC/MNC digit, instead let's put a comment that makes clear which format has to be used.
