hlr: add Check IMEI tests
Create tests for most code paths of rx_check_imei_req() in hlr.c (except for subscriber create on demand, this will be in an upcoming patch). Add missing message types to GSUP_Types.ttcn, and adjust the IMEI and IMEI_Result IEs for consistency with the existing IEs, and to make the tests compile. Related: OS#2541 Change-Id: I97c8462f0817149feadd0c4865e3df6c2af92a80
