[NETFILTER]: Merge ipt_tos into xt_dscp

Merge ipt_tos into xt_dscp.

Merge ipt_tos (tos v0 match) into xt_dscp. They both match on the same
field in the IPv4 header, so it seems reasonable to keep them in one
piece. This is part one of the implicit 4-patch series to move tos to
xtables and extend it by IPv6.
