Flatpak: flatpak: arbitrary write in host context via flatpak build-init PUBLISHED

Description (CNA)

If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal.
