bts: Introduce test TC_tx_power_start_ramp_up_bcch
This test verifies power ramping (up) is working fine during BTS
startup.
config files are updated to make sense:
* "nominal power" in osmo-bsc.cfg reflects correct default nominal tx
power of fake_trx.
* "osmotrx tx-attenuation" in osmo-bts.cfg is removed to let osmo-bts
use the value received through OML (max_power_red 20).
* "power-ramp step-size" in osmo-bts.cfg is increased to speed up the
test. There's no good reason to keep it lower.
