Add agl-drm-lease feature
The agl-drm-lease feature will add the DRM lease manager and client library to the current image. DRM lease support is also added to the kmscube test utility if it is installed.

+Subject: [PATCH] texturator: Use correct GL extension header
+
+gl2ext.h is the extenstion header for OpenGL ES 2.0 and all later
+versions according to the Khronos documentation [1]. gl3ext.h is either
+an empty stub, or may not even exist on some platforms.
