Trac #7641: Install GTK compatibility symlinks using icon-naming-utils package.

The GTK stock icons use pre-standardized icon names.  The sugar theme uses
icon names from

  http://www.freedesktop.org/wiki/Specifications/icon-naming-spec

but GTK still uses its internal names for stock icons.  In order for
stock buttons, icons, and existing GTK applications to be themed correctly,
we need to install symlinks.

This commit adds a build dependency on the icon-naming-utils package,
available in both Fedora and Debian.  Packagers, take note.
