msc: fix f_tc_mt_crcx_ran_reject(): properly handle Iu-ReleaseCommand

Previous commit [1] uncovers a problem in f_tc_mt_crcx_ran_reject():
this function uses as_clear_cmd_compl_disc(), which is expecting
A-interface (GERAN) specific BSSMAP Clear Command.  The Iu-interface
(UTRAN) specific RANAP Iu-ReleaseCommand is not handled at all.

The testcase was passing so far due to a bug in as_optional_cc_rel(),
which would unblock the alt-statemtnt on receipt of CC RELEASE, so
that we would never respond to RANAP Iu-ReleaseCommand.

Let's derive a new altstep from f_expect_clear() and use it.
