bsc CBSP: fix osmo-bsc.cfg to contain 3 BTS with a CBCH 

The bsc/BSC_Tests_CBSP.ttcn rely on a configuration where the first three BTS
carry out SMSCB messaging, and the fourth BTS does not. That requires a CBCH
channel config on bts 0, 1, 2.

Side effects:

- adjust the number of available SDCCH (for TC_chan_exhaustion).

- there now is a CBCH channel description in SI4, add this to
  SystemInformationConfig_default.
