cf3/cf.cfengine3: Stop cfengine3 service on all Debian Edu machines

Esp. cf-execd (calling cf-agent command) clobbers the log on all Debian
Edu clients (Debian Edu 12 and onwards) and thus on syslog.intern (aka
tjener).

In Debian Edu, we use cfengine3 for managing configuration adjustments
via manual invocation of the cf-agent command, but we don't support
(yet?) to use cfengine3 for constant system management.

Partially addresses #1051834.
