Vincent Laporte e3c2934213 ocamlPackages.ocamlgraph: make GTK support optional
When `gtkSupport` is true, additional components are built:

 - a module to render a graph on a GTK2 canvas
 - two GTK-based programs: a graph viewer and a graph editor.

The default is to have `gtkSupport` as it is used in e.g., Frama-C.
