Create a new baremetal element

Rather than using a script to mount the image using nbd to extract the
kernel and ramdisk, make a new element called baremetal, which contains
a cleanup.d script that will copy them out to <image name>.{vmlinuz,initrd}.

This is the baremetal (IE: real hardware) element.
Currently, this element will extract out the kernel and initial ramdisk of
the built image.
