zebra: set the interface link-layer socket address

* kernel_socket.c: (ifm_read) The reorganization from commit
  6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the
  interface link-layer socket address structure on routing socket
  platforms.  This restores saving the link-layer information because
  it might be used elsewhere: rtm_write() when no gateway is given,
  if_dump_vty() and rtadv_send_packet().
