values: Use v_pointer for g_value_set_gtype()

... and g_value_get_gtype(). G_TYPE_GTYPE is a pointer type, so it's
values should use the v_pointer member. This is especially true, because
the value collectors from varargs in gvaluecollector.h use that, too.

This should only cause issues when sizeof(glong) != sizeof(gpointer),
and I'm not aware of any such platform. Maybe win64?
