BTS_Tests: add FAACH to TC_meas_res_speech_tchX 

The current TC_meas_res_speech_tchX tests only test a pure voice
transmission. A voice transmission can be occasionally interrupted by
FACCH transmissions. This should also be tested. Lets ad a _facch
variant for the two speech test variants we already that injects a FACCH
from time to time.
