image_types.bbclass: Populate cpio /init as symlink
For cpio/ramfs the kernel will first attempt to execute /init and will
emit the following error as the file is empty:
Failed to execute /init (error -13)
If /sbin/init exists symlink to it so the kernel can immediately start
the correct init executable instead of an empty file.
