This avoids importing ContentWebRTC.jsm just to register observers
that may never observe anything. Avoiding importing .jsms reduces
memory usage.
ContentObserver.js gets loaded once per content process, so I think
the ._initialized stuff is not needed in the process script.

This retains the advantage of running only once per process, while
avoiding the per-process overhead of a jsm.
