[PtP] Fix BSD problems with PtP interfaces: must treat RTA_BRD as peer address

	* kernel_socket.c: (ifam_read_mesg) Grab RTA_DST and RTA_GATEWAY
	  addresses from the message (if present, which seems unlikely on
	  current BSD platforms), and show them in the debug messages.
	  Also, add ifam_flags to the debug messages.
	  (ifam_read) If the interface is point-to-point, then the RTA_BRD
	  address should be treated as a peer address.
