    netinet6: Add sysctl flag CTLFLAG_TUN to loader tunables
    
    The following sysctl variables are actually loader tunables. Add sysctl
    flag CTLFLAG_TUN to them so that `sysctl -T` will report them correctly.
    
     1. net.inet6.ip6.auto_linklocal
     2. net.inet6.ip6.accept_rtadv
     3. net.inet6.ip6.no_radr
    
    No functional change intended.
