[YouTube] Fix extraction of fps, audioSampleRate and audioChannels fields for ItagItems of live streams and post live streams

Browse source 
These values were only set before for video streams.

A fallback for the audio channels count has been added, in order to prevent exceptions when generating DASH manifests of audio streams: the fallback value is 2, because most audio streams on YouTube have 2 audio channels.
