fix TCH/H for TC_chan_exhaustion

At the moment we use onle TCH/F and PDCH in our osmo-bsc config,
but the tests TC_assignment_codec_amr_h and TC_assignment_codec_h
requre a half rate channel in order to work. Configuring one TCH/F
to TCH/H seems not to hurt any tests except TC_chan_exhaustion

- also regard half rate channels in TC_chan_exhaustion
- change included sample osmo-bsc.cfg
