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.
