networking/libiproute/iplink.c: fix support for older kernels

Browse Source 
- The CAN netlink interface has been added in Linux v2.6.31 with only 3 options [1]:

  CAN_CTRLMODE_LOOPBACK    0x1  /* Loopback mode */
  CAN_CTRLMODE_LISTENONLY  0x2  /* Listen-only mode */
  CAN_CTRLMODE_3_SAMPLES   0x4  /* Triple sampling mode */

  So define the other options.

- IFLA_CAN_TERMINATION has been added in Linux 4.11 [2],
  define it for older kernels.
