* gnu/packages/gnome.scm (gnome): Add gst-plugins-base and gst-plugins-good.
This will allow stock GNOME installs to play Ogg Vorbis files, among other
things. It will also ensure that GST_PLUGIN_SYSTEM_PATH is set to a sensible
value when GNOME is installed to the system instead of the user profile.
