On Windows, sometimes the compare_videos.py script fails because
the inherited stdin handle from the parent process fails.
It seems we can work around this by passing null to stdin to
the subprocesses, since we're not using it anyway.
The errors looked like this:
Traceback (most recent call last):

Add support for --label flag to the frame_analyzer, that
decides what label shall be used for the perf output.
BUG=none
TEST=
Make sure to have zxing and ffmpeg in the PATH.
Create a captured video (from running vie_auto_test custom call)
webrtc/tools/compare_videos.py --ref_video=reference_video.yuv --test_video=captured_output.yuv --frame_analyzer=out/Release/frame_analyzer --label=TEST_VGA
And then inspecting the output that is prefixed with RESULT.

Now that these scripts are called from browser tests, we need to print everything on stdout since the tests will throw away stderr when invoking programs. I chose to assign sys.stderr to sys.stdout. Otherwise I would have missed stuff like parser.error, which print to stderr.
The error message will get improved because the old code did not catch the case when the binary was missing, which lead to a very confusing error when that was the case. This gets fixed now.
