deps: Update titan.ProtocolModules.M3UA to upstream master

MR contained in our fork was merged [1], so we can use upstream again.

[1] https://gitlab.eclipse.org/eclipse/titan/titan.ProtocolModules.M3UA/-/merge_requests/4

This patch doesn't contain an update hash because it was merged as
fast-forward so the commit hash now in master HEAD did not change from
the one in our repo fork branch.

sccp: Fix test rx SLS expectancies

The SLS is the same for all messages in conn being sent in one direction, but
doesn't need to be the same value on both directions.
Since the SLS value on the other direction is not selected by the test
itself, we cannot expect a given specifi value.
Update the test expectancies.

This started to fail since recently libosmo-sigtran started properly
setting SLS values, eg libosmo-sigtran.git
7781eb275da41a9b6b1ea5d8b0e802e87a8e9d53 and
0061e8d0bcba3b0ed5ea255588619627d0975380.

SCCP_Templates: Expect either proto class0 or class1 upon rx SCCP

Until recently, libosmo-sigtran only sent class0, but it is now able to
send class1 too (0061e8d0bcba3b0ed5ea255588619627d0975380).
Adapt the test expectancies.
