[zserv] Update interface flags to 8 bytes wide.

	* if.h: (struct interface) expand flags to 8 bytes.
	* zclient.c: (zebra_interface_{add,state}_read) stream read of
	  interface flags now need to use stream_getq.
	  (zebra_interface_if_set_value) ditto

	* zserv.c: (zsend_interface_{add,delete,update}) if flags are
	  8 bytes now, update to write out with stream_putq.
