[Piglit] [PATCH] util/egl: Fix build for old EGL headers

[Chad Versace]

I broke the build for many people in commit
cf53b461387952b899b4df6ad4164444f8dee670. In that commit,
piglit-util-egl.c and egl_khr_fence_sync.c rely on a very recent
eglext.h to provide the EGL_PLATFORM_* enums.

Fix the build by defining the required enums in
piglit-util-egl.h.

When Piglit gets proper EGL dispatch, problems like this will disappear.
