    kvm: move the NSD transmogrify code to guestbin/start-dns.sh; drop unbound transmogrify
    
    In detail:
    
    - remove the run-once transmogrify code scribbling all over
      /etc/nsd and /etc/unbound
    
      This means that after a reboot, and for that matter:
         $ gmake kvm-downgrade kvm-install
      NIC will contain unmodified /etc/nsd and /etc/unbound
      directories
    
    - modify guestbin/start-dns.sh to:
    
      -- tmpfs mount /etc/nsd/{conf,system}.d
      -- copy in /testing/baseconfigs/all/nsd/{conf,system}.d
      -- invoke nsd directly (lifted from nsd-start.sh)
    
      again, this means that after a reboot /etc/nsd is untouched
