csd_bs_list_to_bearer_cap(): properly initialize bcap fields

Currently this function fails to initialize all bcap fields properly,
so the resulting CC Setup message generated by osmo-msc has some
fields set to reserved/invalid values.

With these changes I am able to establish a data call on TCH/F9.6:

* cap->{mode,coding}: assign default values explicitly;
* cap->radio: value 0 is reserved, set GSM48_BCAP_RRQ_FR_ONLY;
* cap->data.sig_access: value 0 is reserved, set GSM48_BCAP_SA_I440_I450;
* cap->data.transp: this is not a bool, set GSM48_BCAP_TR_{TRANSP,RLP};
* cap->data.{nr_{data,stop}_bits,parity}: set 8N1 by default;
* cap->data.modem_type: explicitly assign default value;
* cap->data.interm_rate: value 0 is reserved, set GSM48_BCAP_IR_{8k,16k}.

The related libosmocore.git patch additionally fixes encoding of the
"Connection element (octet 6c)", so that bcap->data.transp is used.
