V3.9.1 some code cleanup. Deprecated: --sys-admin

# 25.12.2017 V3.9.1     run in detached mode, drop mess of nohup/setsid/script
# 24.12.2017            --dbusdaemon: dropped consolekit, not really useful
#                       --dbusdaemon: switch only for  --tini/--none. Always run daemon for --systemd --openrc --runit
# 22.12.2017            --systemd: create /sys/fs/cgroup/systemd if missing on host
#                       --sys-admin: deprecated thanks to --tmpfs=/run/lock
#                       containersetup.sh collects most former 'docker exec' commands from dockerrc
