Fix ARGB image glyphs on Open GL ES2 or big endian

Change Ie891665ad66e31692b69db02d34be8d303a7d631 accidentially removed
the condition that would ensure ARGB glyphs would get swizzled on OpenGL
ES2.

This patch readds a condition to check that, and also fixes the same on
big endian hosts by reusing the OpenGL ES2 code path.
