[OE-core] [PATCH 2/3] Prepare mesa-dri for weston compatibility

[Alex DAMIAN]

From: Alexandru DAMIAN <alexandru.damian at intel.com>

This patch enables mesa-git to build wayland-compatible
packages for usage with weston.

It adds wayland platform support, packs the wayland-egl
files.

Activate by setting up OVERRIDE for "weston" to get
it to build.
