PCUIF: upgrade to PCUIF v12

We have added an additional bts_model field to the PCUIF_info_ind. This
also means that we have to increment the PCUIF version number since
adding fields is a major change to the protocol. This patch updates the
related TTCN3 record and also increments the PCUIF version number.
