Clone the osmo-ttcn3-hacks and all dependency repositories less often by
moving related commands to the shared debian-stretch-titan image.
Remove the 'git checkout -f -B master origin/master' line, because the
master branch is checked out by default.
While at it, move the shared "git config" commands too, and move them
before cloning the repositories, so they don't run again whenever the
deps change (logic to invalidate the cache if deps change will be added
in the next patch).

Remove leftover from old TTCN-3 build scripts, before refactoring ttcn3
Dockerfiles. This line has already been removed in 357ec806 from 2017 for
ggsn-test.
In osmo-ttcn3-hacks.git, this is only referenced in the obsolete
bin/install.script (looks like we could remove that, together with the
rest of the bin dir?).

Testing FR support in osmo-gbproxy is a bit more complicated
as it involves the "hdlc" net-devices privded by the hdlc_fr.ko
kernel module.
So we need to
* run on a host with actual hdlc net-devices (e.g. dahdi_dyamic_loc)
* move those net-devices into the containers after starting them
* wait for the net-devices to appear in the containers before starting
either gbproxy or the test suite
