Create a YAML metadata file inside the rootfs image
containing information about the environment:
```
/var/lib/osbuilder/osbuilder.yaml
```
Example contents:
```

version: "unknown"

```
This change adds a new `-o` option to `rootfs.sh` for
specifying the version of osbuilder to the rootfs builder.
Fixes#35.

To simplify maintaince, create dockerfiles based on templates.
This way when golang version is updated it will be done in one place
versions.txt.
This also allow to allways intall the same version of golang in any
dockerfile.
