cmdutil.service: move pidfile writing to the parent in daemon mode
There is a potential race here, which I suspect I've spotted in the wild, where
something reads the pid file after the parent exits but before the child has
had a chance to write to it. Moving writing the file to the parent causes this
to no longer be an issue.
