cronie: prevent from failing without sendmail
If a job produces output cronie will attempt to send it's output with
sendmail, failing if the command doesn't exist. sendmail failures are
not handled gracefully and will result in remaining cron scripts to not
be executed. The change makes cronie service use syslog so cron jobs
that produce output are working out of the box.
