MSC: add test cases for concurrent MO/MT SS/USSD transactions

Both test cases make use of the existing functions:

  - TC_multi_lu_and_mo_ussd: f_tc_lu_and_mo_ussd_single_request(),
  - TC_multi_lu_and_mt_ussd: f_tc_lu_and_mt_ussd_notification(),

starting several (*) BSC_ConnHdlr components in parallel.

(*) The maximum amount is limited by 8, and this limitation seems
    to be caused by size of GSUP_Emulation_CT.GsupExpectTable[],
    even despite SCCP_Emulation can handle twice more.
