initramfs-boot: create /dev/console

The Yocto kernel expects a proper /dev/console to exist before running init,
otherwise booting will fail with the message:

  Kernel panic - not syncing: /dev/console is missing or not a character device!
  Please ensure your rootfs is properly configured

Add similar fix as was done for initramfs-framework and initramfs-live-boot
in commits
