bsc: Don't expect BSC to release SCCP in LCLS.TC_lcls_connect_clear() 

While osmo-bsc was still affected of OS#3331, it would release the SCCP
connection from the BSC side.  This is illegal as per 3GPP spec and
has meanwhile been fixed in osmo-bsc master.  However, the testcase
BSC_Tests_LCLS.TC_lcls_connect_clear() relied on the broken behavior,
let's fix that.

The testcase now releases the SCCP connection from the simulated MSC
side in response to the BSSMAP Clear Complete from the BSC.
