Describe the bug
the bzimage package can't unpack kernels compress with xz. This is because when I wrote it I was not sure how to find
the compressed part and used a simple minded search.

To Reproduce
create a bzImage but enable XZ compression in the kernel (yep, it's still called a bzimage)
use the kexec command with debug and note you see this:
