net-netlink: Add a new attribute to expose TCLASS values via netlink
commit 3ceca74966
added a TOS attribute.
Unfortunately TOS and TCLASS are both present in a dual-stack v6 socket,
furthermore they can have different values. As such one cannot in a
sane way expose both through a single attribute.
