retrace: Fix cron job definitions

* Fix line folding syntax. The previous version caused vertical
  whitespace to be included in the output which broke the crontab.
* Rename clean up job so that it doesn't contain any variables.
  Including variables in a name makes it difficult to remove or change
  the job when the variable changes.
* Code style consistency.
