MSC/Iu: fixup: start 16 BSC_ConnHdlr components in parallel

Since Ibca0e9196c25ab00803041b81f7b490ba2f0a3ba we can have up to
16 components of type BSC_ConnHdlr running in parallel. Both
TC_multi_lu_and_{mo,mt}_ussd test cases have been updated,
but their Iu/UMTS siblings have not. Let's fix this.
