debian-stretch-titan: Use osmocom build of titan 6.3.x

Debian 9.0 ships with titan 6.1.0 which for some unknown reasons
causes segfaults in the C++ part when parsing CTRL messages and
according to TITAN project is not supported anymore anyway.

So let's use a 6.3.x build, or whatever is the highest version in
the network:osmocom:latest feed instead.
