Improve testing of SRTP external auth code paths.
Previously code behind ENABLE_EXTERNAL_AUTH was only compiled with Chromium
but developed in WebRTC, which made testing rather complicated. This caused
some trouble in the past (e.g. https://crbug.com/628400#c1)
This CL helps in that the external auth code is now compiled with WebRTC
and the srtpfilter integration gets tested.
