[BUG] Crash when extracting file with hardlink to itself

[0xE1E10]

See devcontainers/cli#699 for details

/workspaces/cli/dist/spec-node/devContainersSpecCLI.js:6107
        return paths.every((q) => q[0] === fn) && dirs.every((q) => q[0] instanceof Set && q[0].has(fn));
                                   ^

TypeError: Cannot read properties of undefined (reading '0')

Root cause: devcontainers/cli#699 (comment)

Why do we have these?

This happens if a file is specified multiple times indirectly by the directory when it is created. libarchive/libarchive#1381 (comment) Apparently both GNU tar and libarchive just ignore this kind of silly links instead of fixing the problem. It's stupid but might want to do the same for compatibility.

Verified that in v7, this is just a warning, not a crash.
