bts: Update towards most recent "laforge/trx" branch

The existing BTS testing code was based on a ~1 week old version
of trxcon+fake_trx from osmocom-bb.git fixeria/trx branch, which
has meanwhile evolved:

* port number change for TRX protocol
* FAKE_TIMING -> FAKE_TOA
* we can now expect responses to our UDP control commands

Let's adapt the testsuite to those changes
