bsc: Add TC_chan_rel_hard_rlsd_ms_dead
In this test case, the MSC performs a hard SCCP release of the
SCCP connection. This makes the BSC send a RLL REL REQ on the lchan,
but we simulate a broken/lost MS which doesn't respond to that.
Current OsmoBSC master will fail this test, and that's exactly why we
need it.
