mesa: Add Mesa 11.0.1 recipe

* Includes experimental EGL library
* Software Rast is no longer a thing on Haiku
  but older mesa_swrast packages can be used
  on later versions of our OpenGL kit.
* There are some bugs, so lets wait a few revs
  before using these packages in the build.

+SUMMARY="Multi-platform GL implementation"
+DESCRIPTION="Mesa is an open-source implementation of the OpenGL \
+specification. The OpenGL specification documents a system for rendering \
+interactive 3D graphics. Mesa fills the role of the Haiku OpenGL kit \
+providing 3D rendering to Haiku applications."
