[yocto] Setting root password

[Daniel.]

My image .class file has includes a lot of recipes that I wrote for
specific reasons so it will not work as it is for you without that recipes,
instead here is the minimal you may need to get this working. I use a class
file because I have lot of images differing in little things, like which
kernel modules are auto loaded. So for your case I think this simple recipe
would suffice. If you want you can save this as .class file and import from
other images as I do.
