EXA: Don't use exaGlyphs if the driver doesn't provide a PrepareComposite hook. 

It's buggy without Composite acceleration (leading to cropped glyphs) and not
really useful in that case anyway. The bug probably still needs to be found and
fixed for drivers that provide a PrepareComposite hook but can't accelerate
text rendering though.
