Launch Xorg server direct from supervisor rather than a script

- Remove launcher for X11 and just call it from
- Improvements to the '/tmp/.X11-unix' directory
    - Move lockfile clearing to init script rather than launcher
    - Configure the 'XDG_RUNTIME_DIR' to something that is easily shared between containers
- Ensure all logs in home directory are readable
- Log Xorg service in home directory so they are more easily accessable to users
