[pygobject] Initialize the foreign API at PyGI load time

[Simon Feltman <sfeltman src gnome org>]

commit 31ecd935564984068e6646676392122bdc03e42e
Author: Simon Feltman <sfeltman src gnome org>

    Initialize the foreign API at PyGI load time
    
    Initialize the foreign struct list at gi._gi module load time. This ensures
    we always have a valid (non-null) list of foreign marshalers outside of the
    context of marshaling.
