images: add core-image-initramfs-boot
Add a minimal initramfs image recipe that just contains enough initramfs
to find the real root filesystem and pivot to it.
BSPs can use MACHINE_EXTRA_RRECOMMENDS to pull in any kernel module
packages that are required to bring up the hardware so that the rootfs
can be found.
