selftests: net: cmsg_so_mark: test ICMP and RAW sockets 



Use new capabilities of cmsg_sender to test ICMP and RAW sockets,
previously only UDP was tested.

Before SO_MARK support was added to ICMPv6:

  # ./cmsg_so_mark.sh
   Case ICMP rejection returned 0, expected 1
  FAIL - 1/12 cases failed

After:

  # ./cmsg_so_mark.sh
  OK
