    tcp: Add CTLFLAG_VNET flag to some sysctls
    
    The two sysctls net.inet.tcp.hostcache.list and net.inet.tcp.hostcache.histo
    are readonly and are to operate hostcache of vnet jails. Add CTLFLAG_VNET
    flag to them since they are per-vnet sysctls.
    
    This change does not have any impact on reading the two sysctls, but
    `sysctl -ANV net.inet.tcp.hostcache` will report them correctly.
