This commit adjusts the method in which `ca-certificates` is installed into the startup-script image. The `ca-certificates` package has a dependency on OpenSSL, which unnecessarily increases the attack surface of the image, since the image's only functionality is fully contained in `manage-startup-script.sh` and the script makes no network connections. The package could theoretically be removed, but as a precaution, the root certificates from the `ca-certificates` package are copied in to the image using the same method as is used in the Cilium Operator image.
