gst-meta-base: pull in X11 plugins when using X11

The splitting out of X11 plugins wasn't complete, which lead to no X11 plugins
being installed.

If the X11 distro feature is present, make gst-meta-base depend on
gst-meta-x11-base.  Also make -x11-base RDEPEND on xvimagesink for video
playback performance.
