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.
