kernel: Install uncompressed kernel by Image instead of

 vmlinux on arm64

arm64 does not use vmlinux to boot, Image is used instead.

Otherwise, kata can't boot from vmlinux.container

Besides, given that firecracker only supports booting from Image,
don't set vmlinux for firecracker target

Fixes #930
