Remove deliverer systemd files

As reported by Matthew, systemd logs keep spamming
journal with starting and started messages.

I will move to an alternative mechanism based on
cron to trigger deliverer.py regularly.

Update trainee name and school

Some parts of trainees data can be reported later

prepared to update everything that can change.

Use cron jobs to trigger deliverer

This is the replacement for the systemd timers.

A guard file will make sure we don't run into troubles
when deliverer takes longer than 10 minutes and the cron
file will trigger the guard file in that interval.

Another .spec typo fix
