Marco Trevisan (Treviño) fe38a02c62 gmodule: Define a gmodule include dependency and use it in gio modules
Various gio modules include gmodule.h that requires the
gmodule-visibility.h to be already built.

To make this easier, just provide a dependency and use it where we are
building modules that do not depend on libgio_dep (that already includes
that).
