Cleanup systemd unit file

[nhooyr]

• Remove all the extra newlines
• And why do we need /sbin/start-stop-daemon
• Remove User=1000? If they're running the binary and not the container, they don't need to be running as UID 1000, they can chose whatever they want.
• Also don't need service=simple, it's default.
• Restart should be always
• Working directory should be just $HOME

This was a original copy from one of my systemd units, so the plan right now when we closed GH-379 was to fix it some more then PR it in
