Dan Nicholson 5dbbde5b22 Default DRI driver directory to match X.Org xserver 
Since the only valid consumer of the DRI drivers is the X.Org xserver,
this changes the default DRI driver directory to match xorg-server:
${libdir}/dri. The old default of /usr/X11R6/modules/dri was wrong for
nearly all current systems.
