trxcon/trx_if: negotiate TRXD PDU version 1 (TRXDv1)

Now that trx_if.c is built against libosmo-trx, enable TRXDv1 by
negotiating it (SETFORMAT) before every POWERON, since the transceiver
may reset its active format back to legacy on the preceding POWEROFF.

This significantly improves the ttcn3-bts-test pass/fail ratio in the
frequency hopping configuration: TRXDv1 lets the transceiver
(osmo-trx-proxy) send us NOPE.ind, which we rely on to keep driving
uplink bursts even when no downlink burst was received.
