[Piglit] [PATCH 07/10] CMakeLists: only set HAS_X11 if X11_FOUND

[Daniel Kurtz]

It should be possible to have a Linux system without X11.  In fact we
even probe to detect X11.  Let's use the result to initialize HAS_X11.

This patch looks right to me, and works on my X11 Linux systesm.  But, I
don't have a system to test either non-Linux nor Linux-without-X11.
