Python 3.14 added security checks around archive extraction, and by default will refuse to handle symlinks with absolute paths. It's possible to handle this using 'filter' argument, but it is not always available in older Python versions on various host distributions we need to support, so let's extract only the needed files directly using tarfile module. busybox is itself a symlink to busybox.nosuid, so both are extracted.
