    gtypemodule: Cast *_init functions to void(*)(void) first
    
    This is an analogous commit to c1f5e528. The original fix only touched
    gtype.h and not gtypemodule.h.
    
    The *_init() functions have prototypes incompatible with *InitFunc types they
    are being cast to. This upsets GCC 8's -Wcast-function-type that's enabled by
    default with -Wextra.
    
    Let's not have the public header files emit a warning and neutralize it by
    doing a void(*)(void) cast first.
