Add ttcn3-gbproxy-test-fr for FR related testing

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
