This sets TMPDIR to a tmpfs directory shared between the Flatpak vscode and the host, which fixes an issue when using Devcontainers features. Note: TMPDIR is used by Node.js [`os.tmpdir()`](https://nodejs.org/api/os.html#ostmpdir) which is used by [devcontainers CLI](https://github.com/devcontainers/cli/tree/eda6cf892e1440d1fbb454d6e457a2343113ded6).

/tmp is always a private, sandbox-local tmpfs in Flatpak regardless of --filesystem=host, so Node's os.tmpdir() (used by the devcontainers CLI) writes build contexts there where the host-side podman (run via host-spawn) can't see them. $XDG_RUNTIME_DIR/app/<app-id> is the directory Flatpak actually shares with the host for this purpose, per the Flatpak sandbox-permissions docs. Cherry-picked from flathub#606, fixes flathub#605. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
