EXA: Fix acceleration of solid pictures on big endian

On OpenBSD/macppc with drm and UMS ati driver 6.14.5 and 6.14.6, gtk (cairo?)
applications do not render black fonts correctly. 

This does not happen when using 'Option "AccelMethod" "XAA"' nor with the ati
driver version 6.14.4.

I believe the problem comes from an endianness issue related to the support for
accelerated solid pictures added between 6.14.4 and .5. The attached patch
this issue for me, tested on a mac mini (rv280) and powerbook (rv350).

Don't hesitate if you need more information.
