[latexila] Don't use gtk_icon_theme_add_builtin_icon() (deprecated)

[Sébastien Wilmet <swilmet src gnome org>]

commit d3e29d1fdb9a3800203af27c19583740f99c006d
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Fri Jul 11 17:10:03 2014 +0200

    Don't use gtk_icon_theme_add_builtin_icon() (deprecated)
    
    Use gtk_icon_theme_add_resource_path() instead, which is easier to use.
