Add support to Funtoo Macaroni OS

[geaaru]

When the subset portage is enable inside a macaroni installation it's possible use vulner with portage engine but instead if this subset is not enable a possibility could be use the output generated by the luet search --installed . command in the JSON format.

Hereinafter, an example of the output:

$ sudo luet s --installed  -o json  lshw | jq
{
  "stones": [
    {
      "name": "lshw",
      "category": "sys-apps",
      "version": "02.18b",
      "license": "GPL-2",
      "repository": "system",
      "annotations": {
        "subsets": {
          "rules": {
            "devel": [
              "^/usr/include/"
            ],
            "portage": [
              "^/var/db/pkg/"
            ]
          }
        }
      },
      "labels": {
        "DEPEND": "gtk? ( x11-libs/gtk+:2 ) sqlite? ( dev-db/sqlite:3 ) gtk? ( virtual/pkgconfig ) sqlite? ( virtual/pkgconfig )",
        "IUSE": "gtk sqlite static",
        "RDEPEND": "gtk? ( x11-libs/gtk+:2 ) sqlite? ( dev-db/sqlite:3 ) sys-apps/hwids",
        "emerge.packages": "sys-apps/lshw",
        "kit": "core-hw-kit",
        "original.package.name": "sys-apps/lshw",
        "original.package.slot": "0",
        "original.package.version": "02.18b-r1"
      }
    }
  ]
}

My suggestion is for now check if exists the labels original.package.name and original.package.version, and then exclude package without these labels. For the other packages we need to study a different solution but it's a minor number of packages in this condition.

Thanks in advance

Add some more information. After that the repository is been downloaded is available a filesystem tree with YAML files of all packages that could be installed. So for the user case where the vulner tool analyze over all packages available in the repository you can just iterate over the directories under /var/cache/luet/repos/. So, just run:

$> luet repo update

And then parse every definition.yaml and/or metadata.yaml Hereinafter, an example:

$ cat /var/cache/luet/repos/macaroni-funtoo-testing/treefs/net-vpn/openvpn/2.5.7/definition.yaml

hello, @geaaru thanks for this feature request and other details that you provided when we chatted on discord few weeks ago.

I still have this task on my todo list but lacking time to focus more on vulner currently.

let me also do this self-note so that I can jump more easily to this when I'll find some time:
