gtk-icon-utils: Rename, upgrade, add binary

* Rename from gtk-update-icon-cache to gtk-icon-utils to better
  reflect the content. Fix references in other recipes and classes
* Upgrade to GTK+ 3.16.4
* Add gtk-encode-symbolic-svg binary: it is used by icon themes
  (e.g. Adwaita) to generate png versions of svg icons.
* Depend on librsvg-native for gtk-encode-symbolic-svg
* Add a patch that removes Gdk dependency from gtk-encode-symbolic-svg:
  this way the native build stays slim.

+Subject: [PATCH] Remove Gdk-dependency from gtk-encode-symbolic-svg
+
+Building gtk-encode-symbolic-svg without building Gdk is useful
+as only the icon tools are needed on the native build: this makes
+native build much faster and requires much less dependencies.
+
+Upstream-Status: Pending
