Update debian-isogen to use ubuntu style interface names

This change allows the resulting debian live cd to use
ubuntu compatible interface names so that network configuration
for ubuntu hosts can be compatible with this debian live cd

This change also adds utilities to support bonding and vlans
as well as a few critical network debugging tools.
