[OE-core] [PATCH] mesa: clean up PACKAGECONFIG

[Zoltan Gaal]

I'm new to oe, and I've seen there was quite a big discussion about the 
gles support in mesa.
Now libgles-omap3 has the mentioned conflict with the mesa-dri as both 
provides virtual/egl. I think a patch like this would solve the issue:
(mesa-dri is required by xserver, and libgles-omap3 is the accelerated 
gles driver from ti, which also provides egl by nature)
