    lagg(4): Correctly define some sysctl variables
    
    939a050ad96c virtualized lagg(4), but the corresponding sysctl of some
    virtualized global variables are not marked with CTLFLAG_VNET. A try to
    operate on those variables via sysctl will effectively go to the 'master'
    copies and the virtualized ones are not read or set accordingly. As a
    side effect, on updating the 'master' copy, the virtualized global
    variables of newly created vnets will have correct values.
