gtkborder: restore original struct definition

We're going to add back the original struct definition removed by
a6e4de28, because using the typedef breaks all sorts of things like
gtkmm and WebKit, and having separate struct definitions allows us to
change the types in GdkBorder from gint16s to gints without breaking
ABI.
