Libvpx waterfall additional changes. The CL http://review.webrtc.org/595005/ was not complete since it didn't put the libvpx waterfall at its own port.

Chrome bots are now using the correct scheduler.
Created separate watchlist e-mail for libvpx builds to avoid spamming WebRTC when these builds fail.

BUG=None
TEST=Tested on local master and slaves.
