check permissions on file

[shadiakiki1986]

I just encountered a case where the cron file is valid, but the permissions on the file allowed write by "other". A chmod o-w file fixed it, and chkcrontab did not capture this as I assume it doesn't check the file permissions. When the cron service started, it was not processing the file, throwing an error in /var/log/syslog: ffamfe_da_cron_1 | Jan 18 12:16:01 ffa24 cron[1084]: (*system*ffamfe_da) INSECURE MODE (group/other writable) (/etc/cron.d/ffamfe_da)
