Re-comitting r5711: "Fixing a flaky test in video_engine_tests"

The CL was reverted in r5712, due to bots going red. However, these bots
are unrelated to this CL.

Original description:
VideoSendStreamTest.SuspendBelowMinBitrate was flaky. The problem was
that when the first non-padding packet was sent after the stream was
resumed, the statistics had not always been updated so that
stats.suspended was false. After seeing the first non-padding packet
after suspension, the test will now go into a state where it waits for
the statistics to be changed.

Exclude WebRtcVideoMediaChannelTest.AddRemoveCapturerMultipleSources for Valgrind on Mac

This test seems to crash the bot running memcheck on Mac 10.6 at:
http://build.chromium.org/p/client.webrtc.fyi/builders/Mac%2010.6%20Memcheck
over and over again. I won't file a bug since it's unlikely this
will get fixed as long as Valgrind is not supported on newer OS X
releases.
I mainly wanted to make this bot work better so we can one day start
fixing the leaks it's reporting. One step at the time.
