Remove everything unrelated to DataChannels

[aisouard]

There are more than 3,000 files to build, the libwebrtc library only needs about 300 files because they've removed every dependencies to video and audio modules.

We should remove everything related to audio and video codecs.

Here's a list of every libraries compiled and needed by Peeracle, put a ☑️ when you've managed to remove a useless dependency.

It's compiling 851 files right now under Linux since a144c46, but libwebrtc is still building ~300, something's missing.

[aisouard]

Reverted in 311be9c, we should treat issue #2 and #3 before optimizing this.

Edited with a list of libraries to remove.
