Expect YUV to RGB to match exactly for C and SIMD

Browse Source 
Unit tests to convert YUV to RGB previously allowed some error
for differences in implementation between C and SIMD versions,
and there were differences with Intel SSE2 vs ARM NEON.
Now those differences are resolved, the unittest can expect
exactness.

Bug: libyuv:447
Test: LibYUVConvertTest.I420ToARGB_Any
