mesa: fix EGL compilation without X11 headers

Extracted from "d7033f4 mesa: upgrade to 9.1.3", already merged in master.

Add EGL-Mutate-NativeDisplayType-depending-on-config.patch to build correctly in
a non-X11 environment, it replaces fix-egl-compilation-without-x11-headers.patch.

The new patch fixes compilation issues for components that include
EGL/eglplatform.h file. With the original patch it was required to use
-DMESA_EGL_NO_X11_HEADERS when using mesa .h files to get proper C definitions.

The new patch was backported (trivial) to mesa 9.0.2 which is in dylan.
