sys940x.conf: add EMGD VA components to VA_FEATURES variable

The following EMGD subpackages provide video acceleration and have
dependencies on libva and libx11:

  emgd-driver-video
  emgd-gst-plugins-va-0.10.10
  emgd-gst-plugins-mixvideo-0.10.34

Include these in the VA_FEATURES variable only when the EMGD XSERVER
is included in the image.

For images such as core-image-lsb which do not include X components,
including any of these emgd subpackages will pull in unwanted X
components.  This fixes that problem.
