bsc: Expect number-of-broadcadsts-completed-list in CBSP KILL COMPLETE

When responding to a CBSP KILL with a CBSP KILL COMPLETE, make sure
we include the optional "Number of Broadcasts Completed List" IE
in order to inform the CBC about how many times the just-killed
message had been broadcast before it was killed.

It seems some CBCs expect this IE to be present, while 3GPP TS 48.049
lists it as optional.  osmo-bsc is including this IE as of Change-Id
I47aebd613dfc6dd9261ea9019a51aff0cd6470d8

This change updates the test suite to expect this IE to be included.
