machine/qemu: Fix OpenGL/GLX support with xserver-xorg.

  * The Xorg server needs to load the GLX extension in order to
    enable proper OpenGL support.

  * Before this patch, glxinfo aborted with:

      root@qemux86:~# glxinfo
      name of display: :0.0
      Error: couldn't find RGB GLX visual or fbconfig

  * After this patch, it works as expected:

      root@qemux86:~# glxinfo | grep " render"
      direct rendering: Yes
      OpenGL renderer string: Software Rasterizer
