trxcon: do not advance Uplink TDMA Fn by default
The idea behind advancing Uplink TDMA Fn is to give the transceiver,
which is usually a separate process, some additional time to receive
and prepare Uplink bursts for transmission. This comes at a price
of having an additional delay between Uplink and Downlink.
Given that trxcon, as a standalone application, is primarily used in
conjunction with fake_trx.py for running ttcn3-bts-test against
osmo-bts-trx, there is no reason to advance the Uplink TDMA Fn.
