For `go-mysqlbinlog` and `go-canal`: return an error for invalid flavors. For `go-mysqlbinlog`: log a non-critical error if the server version has "MariaDB" in it but the flavor isn't set to "mariadb".

If there is an good way to make it auto detect the flavor this would be even better |

The server returns MariaDB but our flavor requires lowercased, this is a bit uncomfortable. I orefer we let ValidateFlavor ToLower the string before compare.

And I think we can add comment to explain why this is only a log not a failure to caller, like "MariaDB still sends binlog events in a compatible way although some functionalities are lost, so we just log the problem"
