Thomas Goirand 266f24c450 Fix setting-up Buster's backport repository
In buster, using this to install a keyring package doesn't work anymore:
apt-get -y --allow-unauthenticated install keyring-package

Therefore, we must fallback to installing the key manually with apt-key
instead, which is what this patch does.
