msc: add TC_lu_imsi_auth_tmsi_encr_3_1_no_cm

This is a variation on TC_lu_imsi_auth_tmsi_encr_3_1 that "indicates" inability
of A5/3 by completely omitting a Classmark2.

Add flag send_cm_update to f_tc_lu_imsi_auth_tmsi_encr_3_1() so that we can
easily omit the classmark update. Set this flag to true in existing
TC_lu_imsi_auth_tmsi_encr_3_1, and add pass false from the new test.
