[PATCH] xserver: include GL CFLAGS in dixmod build

[Jesse Barnes]

Found this:

make[5]: Entering directory `/home/jbarnes/working/xserver/hw/xfree86/dixmods'
  CCLD   librecord.la
  CCLD   libdbe.la
  CC     glxmodule.lo
In file included from glxmodule.c:44:0:
../../../glx/glxserver.h:56:19: fatal error: GL/gl.h: No such file or directory
compilation terminated.

when trying to build the tree at an alternate prefix without the GL
headers installed in the normal location.  So add the GL CFLAGS to pick
up the pkgconfig include path correctly.
