systemd service cleanup

* Remove requires+after to the same named socket. A socket unit will
  automatically trigger a service if something wants to talk to it. You
  will only ever need to enable the socket unit and don't have to
  explicitly enable the service unit.
* Remove full path for the ini file, since `WorkingDirectory=` already
  puts the process in that directory.
