add msc_vlr_test_call to reproduce a sanitizer error

On MT call, there is a bug in CC conn use which leads to an early free and
use-after-free.

Add msc_vlr_test_call to show both MO and MT call legs separately and reproduce
the failure. It is visible in a sanitizer build (on debian 9).

A subsequent patch will fix the bug: If0659a878deb383ed0300217e2c41c8c79b2b6a5
