Add libyuv_unittest_apk target to run tests on Android

Roll chromium_revision bfea27a..bb79186 (340499:353481) in DEPS.
Changes: https://chromium.googlesource.com/chromium/src/+log/bfea27a..bb79186

To get the Android dependencies, you need to have
target_os = ["android"];
added to the end of your .gclient file (after the solution specs)
+ re-run gclient sync.
You'll also need to run: build/install-android-sdks.sh

Then build and run the test with something like this:
GYP_CROSSCOMPILE=1 GYP_DEFINES="OS=android component=static_library target_arch=arm" ./gyp_libyuv
ninja -C out/Release libyuv_unittest_apk
util/android/test_runner.py gtest -s libyuv_unittest --verbose --release

Finally something that works. I ran into trouble due to some strange thing
caused by the fact that the target starts with 'lib', which made it impossible
to use the build/apk_test.gypi file we use for WebRTC.

I've run the test locally using this, although not all tests passed on my Nexus
7, which I'm not sure why. 

Please try this out.

Looks like this broke a couple of bots (trybots also didn't pass so I was
planning on addressing that first).
I think it's all infrastructure related, since the libyuv bots haven't gotten
any love for a long time. I'll see if I can sort it out.

I've fixed all libyuv bots now :) Android slave needed to get new libs installed
and Windows slaves needed a bump to be able to sync past the massive Blink merge
into Chromium.

Finally the Mac ASan bots have been failing for a long time due to me
configuring them incorrectly (LSan is enabled by default for ASan, but is not
supported on Mac). That was fixed in https://codereview.chromium.org/1401313002
