Andrej Valek b01dd27a8d kernel-fitimage: use correct kernel image 
Even if initramfs_bundle_path was used, a wrong compression was reflected
in output its template file. Use linux.bin as universal kernel image.
The linux.bin file covers both cases because it's beying created from
vmlinux.

We know, that vmlinux is created inside compressed directory already,
so no external compression will be used.
