fix octphy, fix conf, improve logging

Clearly separate the kinds of BTS hardware the GSM tester knows ('type') from
the NITB's bts/type config item ('osmobsc_bts_type' -- not 'osmonitb_...' to
stay in tune with future developments: it is the libbsc that needs this).

For BTS hardware kinds, use the full name of the binary for osmo driven models:
osmo-bts-sysmo, osmo-bts-trx, osmo-bts-octphy.
