Fixes for vCPE vG-MUX install script

Fixes for vCPE vG-MUX install script

Addresses the following items:
- Do not setup auto configuration for eth1 and eth3
  These interfaces will be used by vpp so they need to be down
- Fix pci bus numbering for vpp interfaces
- Fixes to properly create the 'save_config' script
- Install linux-image-extra package to get uio_pci_generic
  driver module for the vpp dpdk interfaces
- fix build of honeycomb so the jvpp-ves module built by vpp
  can be found
- Patch libevel.so code to tweak the VES data produced
  so that sourceId and sourceName come from the openstack
  vnf_id property (instead of vm_uuid and vm_name)
