BTS_Tests: introduce TC_speech_no_rtp_{tchf,tchh}

The purpose of these new test cases is to demonstrate a problem
described in OS#4823: the IUT sends *dummy bursts* in absence of
MT RTP frames, so on the MS side it looks like RF failures.

It's not yet clear what needs to be sent by the BTS in this kind
of situation, but at least we can verify that whatever is sent
can be decoded on the MS side without CRC errors.
