Summary

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 does not have any impact of
reading the two sysctls, but sysctl -ANV net.inet.tcp.hostcache will report them
correctly.
