Daniel Willmann 0886215539 msc: Avoid race condition when setting osmux options via VTY
If the RAN_Emulation is started before the VTY reconfiguration we could
get a BSSMAP Reset/ResetAck with Osmux support advertised even though
the test expects it to be disabled (or vice versa).

Do the VTY configuration before starting the RAN_Emulation.

Fixes sporadic/load-related TTCN3 failures with message
"BSSMAP: Timeout waiting for RESET-ACK after sending RESET"
(e.g. TC_iu_and_mt_call_osmux, TC_iu_and_mo_sms in run +1567)
