interfaces: loopback "lo0" exists for VIPs

Historic oversight of wedging in a loopback interface in virtual IP
section while not making sure the actual configuration receives a
virtual IP when it needs to.  This was previously fixed by a batch
VIP regeneration in interfaces_configure() but we already saw that
this is not needed in 99% of the cases.
