Bug description:
  [Impact]

   * Canonical OEM IBS still uses Ubuntu 12.04 to build Ubuntu OEM images for
     trusty, wily and the following xenial.

   * Without this fix, Canonical OEM IBS can not generate Ubuntu OEM
  images for wily and xenial.

  [Test Case]

   * Please use the config in comment #7.
   * Uncompress it and execute `lb build` on Ubuntu 12.04.
   * It should be able to generate a binary.iso.

  [Regression Potential]

   * None

  [Other Info]

   * The fix for precise in attached in comment #6.
   * This issue only affects precise.

  When LB_INITRAMFS="casper", lb_binary_disk assumes initrd is
  compressed with gzip. Since it can be lzma and bzip2, build process
  will fail if one of those two compression methods are used. This is
  fixed upstream by commits 1940 and 2105. Patch is attached.
