By using initramfs for the rescue we occupy 8mb + ~3mb for the
kernel and can reduce the size of that slot. With glibc it is
difficult to reduce this even further. Let's see if a uclibc
build can help us
Splitt of the actual rescue root filesystem to
image-rauc-rescue-initramfs and build image-rauc-ubi using
kernel+initramfs (like normal rauc slots).
