    GsdSmartcardService: Use correct parent type for structs
    
    GDBusObjectSkeleton objects are larger than GObject, so we need to

        Sep 13 11:09:32 espresso gsd-smartcard[12882]: specified class size for type 'GsdSmartcardService' is 
smaller than the parent type's 'GsdSmartcardServiceManagerSkeleton' class size
        Sep 13 11:09:32 espresso gsd-smartcard[12882]: g_type_add_interface_static: assertion 
'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed
    
    and if we're unlucky we'll get object fields overwriting each other.
