Bug 1127448 - Append the build id to the ua string for youtube. r=mconley

Browse Source 
We want to be able to distinguish different builds to track
down crashes and other problems with the YouTube site. Pushing
the build id lets google group statistics from their logging
in the same bins for comparison.

Limited by #ifdef MOZ_UPDATE_CHANNEL to beta, aurora, and nightly.
Limited by media.mediasource.enabled pref.

We put this in nsBrowserGlue.js instead of browser.js so it runs
once, rather than once per window like the fennec implementation
we copied. They only ever have one window, so it's ok there.
