[mono-repo-merge] Move linux-loader to rust-vmm #19

Open PR with the merge of linux-loader into rust-vmm

• In linux-loader/Cargo.toml, change the repository field to repository.workspace = true
• In linux-loader/Cargo.toml, change all dependencies for rust-vmm crates that are part of the workspace to use the local path in addition to the version (i.e. vm-memory = { path = "../vm-memory", version = "0.18.0" })
• Update CODEOWNERS
• Update gitignore if needed
• Update audit.toml (check whether it's ok to have one per crate instead of one in root)
• Update github workflows

Post Merge Actions

• Move all issues still open from to the rust-vmm repo
  • Open each single issue
  • Click on -> Transfer issue button
  • Select rust-vmm repo
• Ask to move open PRs
  • Close the PR (there is no way to move them)
  • Leave a message for the author asking to re-open it in the new rust-vmm repo (e.g. @ <pr-author> are you still interested in getting this PR merged? If yes, could you please re-open it in https://github.com/rust-vmm/rust-vmm/. We moved <original-repo> there.)
• Move security advisors (it seems there is no way to move them, so we need to close and re-create)
  • Add a reference to the original one
  • Copy all the discussions to the new one

Archive the repository [NOTE: only maintainers have permissions to do these actions)

• Update the About section of the repository to specify that it's now an archive and the code was moved: "This is a public archive. The code now lives in the mono-repo: https://github.com/rust-vmm/rust-vmm/"
• Archive the repository
