- Update list network interfaces win32 variant 

Some utilities such as netsh require a friendly name when doing
  any administrative tasks such as stop/start network interfaces.
  Currently sigar list network interfaces as 'ethX, lo, laX'. This
  is fine for read only purposes but in order to make further use
  of the network interfaces on windows we need a friendlyname or at
  least the interface description.
