Only copy the kernel if we're running on an old-style image
Only copy the kernel if we're running on an old-style image

but old-style images need to extract the kernel from the filesystem and
copy it to the EFI System Partition themselves. Make this behaviour
conditional on the app ID that Update Engine passes down.
