Revert of Distance field fixes for Android (https://codereview.chromium.org/205343008/)

Reason for revert:
compile error at line 110 in GrDistanceFieldTextureEffect.cpp

Original issue's description:
> Distance field fixes for Android
> - Expand glyph size by 2 on each side to compensate for bilerp lookup
> - Correct for Adreno tendency to drop entire tile if any pixel has divide-by-0
> - Fix blurriness on Adreno by using uv coords to compute gradient instead
>   of st coords
> - Add faster version for uniform scale
>
