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.
