Marco Trevisan (Treviño) 341895a19e glib, gmodule, gobject: Add generated headers to the lib dependency
This requires changing them from being generated sources at compile time
to custom targets, but it also ensures that they are actually there when
needed, in fact currently we may instead try to compile files that requires
them without having been generated yet.
