Add dependency

gtk applications need librsvg2 to render SVG icons (if they are used in the current theme).

To do this an application dynamically loads /usr/local/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so (this lib installed by librsvg2).

Hot to reproduce the problem:
1. pkg delete librsvg2
2. run 'env GTK_THEME=Adwaita gtk3-icon-browser'

- in "Symbolic" tab/mode grey rectangles will be shown instead icons
- grey rectangles will be shown instead search, minimize and maximize window icons

The same problem can be seen in other gtk3 applications (but only some icons will be missing because raster icons will continue to work).

Problem can be fixed by installing librsvg2 back.

librsvg2 is an optional dependency for gtk, because it is possible to use a theme with only raster icons (and in this case librsvg2 will not be used), but given that SVG icons are used in default theme, I think this dependency should be added.
