[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]

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.
