Explicitely add needed include arguments as well as linker arguments for gmodule. Before this change we relied on gmodule being an implicit dependency pulled in via the gtk+-2.0 module, this does not seem to be the case anymore with >=gdk-pixbuf-2.24 and >=pango-1.30. Thanks for Alexandre Rostovtsev for bringing this up on the mailinglist and for providing a first patch. See also https://bugs.gentoo.org/show_bug.cgi?id=428532
