Adding missing flags for OCI Layout to restorer

[jjbustamante]

Summary

This PR adds the layout and layout-dir flags to the restorer phase when the PLATFORM_API version is equal or greater than 0.12.

It also fixes an issue when the run-image is read from the analyzed.toml file we will get something like:

{
"Reference":"",
  "Image":"/layout-repo/index.docker.io/cnbs/sample-stack-run/jammy",
   "Extend":false,
   "target":{
     "os":"linux",
    "arch":"amd64"
 }
}

We were trying to parse the Reference.Image into a path, but it is already a path, so we don't need to do anything in that case.

Release notes

When using platform API 0.12 or greater, The layout flags layout and layout-dir were exposed in the restorer binary
