Fix OVA generation and add grub label helper for ubuntu-cpc

[ Chris Glass ]
* Fix the manifest generation in OVA files so that ovf files don't have
  double extensions.  (LP: #1627931)
* Fix the OVF's metadata to include Ubuntu specific identifiers and
  descriptions instead of the generic Linux ones.  (LP: #1656293) 
[ Daniel Watkins ]
* Add replace_grub_root_with_label function thereby consolidating multiple
  uses of the same calls to sed.
