nixos/docker-containers: Move ExecStartPre/ExecStopPost to preStart/postStop
This commit fixes #76620. It moves ExecStartPre and ExecStopPost to
preStart and postStop, as these options are composable. It thus allows
adding additional initialisation scripts or cleanup scripts to the systemd
unit of the docker container.
