stp: Ignore M3UA SSNM messages in tests
The tests were written without considering the arrival of such messages;
however, it is well within the M3UA spec that such messages appear at
any time indicating remote point code availability etc.
In libosmo-sccp.git Id92be4691b0fd77598a6edb642c028bbd8c5b623 we start
generating those messages in osmo-stp.
Let's ignore them in the tests to avoid unexpected failures.
Later on, we likely will introduce / adapt tests to actually expect
those messages whenever appropriate.
