The `install_cached_tarball_component` function in the binaries packaging script contained syntax errors where it attempted to capture the empty stdout of the `cleanup_and_fail` function inside a return statement (e.g., `return "$(cleanup_and_fail ...)"`). Since `cleanup_and_fail` only returns an exit status and produces no stdout, this evaluated to `return ""`, which is invalid in bash and causes the script to crash with `numeric argument required` instead of returning the failure status. Fix this by replacing the buggy inline returns with proper `if` blocks that call `cleanup_and_fail` and explicitly return `1`. Signed-off-by: Huy Pham <huypham@google.com>
