Revert "Switch default color format to YV12."
This reverts commit 1c3e728aa9b886fd3ee008a5aed956759bc3f82d.
Reason: Fails test running on Nexus 9 bots - org.webrtc.VideoCapturerAndroidTest#testStartStopWithDifferentResolutions.
Note that all other tests pass so it seems like there is resolution supported by the device that can't use YV12.
