libva-intel-driver: Disable X11 and Wayland.

This CL explicitly disables X11 and Wayland for libva-intel-driver
because we never use VA-API over X11 or Wayland on Chrome OS. This
involves removing the corresponding IUSE flags.

This is a cleanup to make it possible for the libva uprev to also not
involve IUSE flags that we don't care about.

Note that it is not necessary to pass --enable-drm: this is not a
supported flag [1].
