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).
