msc: Permit optional authentication before reject/timeout

Tests like TC_lu_imsi_reject, TC_lu_imsi_timeout_gsup and
TC_cmserv_imsi_unknown all expected a reject straight in response
to the LU REQ / CM SERV REQ.  However, the MSC may very well decide
to perform authentication beforehand.  It's an implementation
detail when a MSC/VLR performs authentication, so the tests should
be tolerant to this.

This primarily shows up in 3G/Iu/RANAP related tests, as authentication
is mandatory there.
