kwiberg 7a12b5ad8e Run some peer connection end-to-end tests with an empty audio decoder factory
Specifically, the tests that only use data channels shouldn't need any
audio codec support; by using an audio decoder factory that supports
no codecs, we ensure that this is the case.

For completeness, I tried doing the same to the two tests that
actually use audio and video; as expected, they fail, with messages
like this:

  [000:032] (webrtcsession.cc:334): Failed to set remote sdp: Session
  error code: ERROR_CONTENT. Session error description: Failed to set
  local audio description recv parameters..
