Benjamin Otte a15fb95c46 gtk-demo: Use normal way to lookup up symbols
We're a normal application, so we can use the normal way to hook up code
into builder files, which is using dlsym() for the function pointers.

There's no need to to extra work exporting static symbols.

/* Model Button
*
* GtkModelButton is a button widget that is designed to be used with
* a GAction as model. The button will adjust its appearance according
* to the kind of action it is connected to.
*
* It is also possible to use GtkModelButton without a GAction. In this
* case, you should set the "role" attribute yourself, and connect to the
* "clicked" signal as you would for any other button.
*
* A common use of GtkModelButton is to implement menu-like content
* in popovers.
