Subject: [PATCH] armbian-truncate-logs: Use journalctl --quiet (#3684)

By default, cron sends an email to the system admin if it finds anything in the stderr of the process.
journalctl sends "diag output" to stderr (see https://github.com/systemd/systemd/issues/380).
The easiest way to prevent sporadic emails is to call journalctl with --quiet.
