Kristof Provost 2ca5f390c4 Allow more services to run in vnet jails
After some tests, here are the services that run into a vnet jail:
  - defaultroute
  - dhclient
  - ip6addrctl
  - natd
  - pf
  - pfsync
  - pflog (deamon runs, pflog0 interface usable, but /var/log/pflog not filled)
  - rarpd
  - route6d (do nothing anyway because obsolete)
  - routed (do nothing anyway because obsolete)
  - rtsold
  - static_arp
  - static_ndp
