blitframebuffer-test.html failed on Mac and Linux

Project Member Reported by yunchao...@intel.com, Sep 9 2016 
blitframebuffer-test.html failed on Mac and Linux (It probably fails on Windows too). 

According to GLES spec, if src buffer and dst buffer has image identical (the same renderbuffer, or the same texture with the same face and the same mipmap level and the same layer), it should generate INVALID_OPERATION. 

This behavior is like Feedback loop detection for some API, say CopyTex{Sub}Image{2D|3D}. 

Chrommium doesn't impl this feature, so this test case failed.
