bash-completion: rework startable/restartable units once more
I tried to use 'systemctl --all list-units' to filter unit files, but this always filters out unit files which are not loaded. We want to complete systemctl start with those units too, so this approach is not going to work. New version is rather slow, but hopefully correct.
