Xwayland patch to fix build

Buiding just released xorg 1.20, I found it does not compile from source.

The error is:
../../../hw/xwayland/xwayland-glamor.c: In function ‘xwl_glamor_egl_device_has_egl_extensions’:
../../../hw/xwayland/xwayland-glamor.c:117:42: error: ‘EGL_PLATFORM_DEVICE_EXT’ undeclared (first use in this function); did you mean ‘EGL_PLATFORM_X11_EXT’?
     egl_display = glamor_egl_get_display(EGL_PLATFORM_DEVICE_EXT, device);
                                          ^~~~~~~~~~~~~~~~~~~~~~~
                                          EGL_PLATFORM_X11_EXT

These are the option I use to build xserver:

You can find attached patch I used to make it build.
