Disable the WIC encoder for jpegs

Browse Source 
My fix from https://codereview.chromium.org/1791583002/ is not
sufficient.

WIC will only encode JPEGs if we pass in a bitmap in BGR
format.  For now, let's disable the WIC encoder on JPEGs
and fall back on SkImageEncoder_libjpeg.

This should fix the scaled-generator gm.
