    netfilter: remove no-op kconfig symbols
    
    These have long been obsolete. For reference, here's the Linux version where
    each symbol has been dropped:
    
    CONFIG_IP6_NF_QUEUE - 3.5
    CONFIG_IP6_NF_TARGET_LOG - 3.4
    CONFIG_IP_NF_MATCH_DSCP - 2.6.19
    CONFIG_NF_CONNTRACK_IPV4 - 4.19
    CONFIG_NF_CONNTRACK_IPV6 - 4.19
    CONFIG_NF_CONNTRACK_RTCACHE - out-of-tree, superseded by flow offloading

    (cherry picked from commit d7956c57284624f4bc7b905d192c81e1d34576fe)
