initramfs-live-boot-tiny: Create the initramfs-live-boot-tiny recipe
The original initramfs-live-boot recipe RDEPENDS on udev, which is ok since
the init script relies some of its functionality on udevadm and such,
but on core-image-tiny-initramfs the init script simply drops to shell
after a basic setup, so udev is not needed.
This patch splits up an initramfs-live-boot-tiny recipe which does not
use udev, but uses busybox-mdev instead, eudev installed about 600
extra Kilobytes to core-image-tiny-initramfs userspace, by avoiding to
install eudev we achieve an even smaller footprint (almost 40% smaller).
