Update apache2_config.c

Change third parameter(which is the apr file permission flag) from CREATEMODE to dcfg->auditlog_fileperms. Due to the user can specify the desired file permission setting for the audit log files with setting the value of SecAuditLogFileMode, we should follow the file permission setting from the config file. Therefore, as the dcfg->auditlog_fileperms will be modified in cmd_audit_log_dirmode function, we can use the value while calling apr_file_open to meet the file permission that specified in modsecurity.conf.
