gnome3.gnome-shell: Clean up

Remove the following dependencies:

* libcanberra – https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/327
* libsoup – https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/234
* libXtst – 9f5a2d8aca
* glibcLocales – no longer necessary since glibc now contains C.UTF-8 locale
* docbook-xsl-ns – not sure why this was included but there are no complaints when this is removed

Also move gnome-autoar & json-glib to proper section and drop unused clutter arg.
