The database audit script fails to run properly on MySQL 8.0.29

[TheWitness]

Describe the bug

Cacti's audit function fails on the latest MySQL due to Oracle breaking backward compatibility which will likely additionally break the zero fill feature in MariaDB/MySQL. Oh well. Reported here. #4886.

To Reproduce

Steps to reproduce the behavior:

1. Install Cacti using MySQL 8.0.29

2. Attempt to run the audit_database.php using the --report option

3. Note it things things are wrong

Expected behavior

Cacti should work with MySQL. Bad Oracle! I know why you did this, but there were reasons it was stupid in older MySQL too.
