eWay - improvement - allow it to cope if open_basedir is set without error

On servers where open_basedir is configured eWay payment processor presents an error message.

warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set in /var/www/d6c22-html/sites/all/modules/civicrm/CRM/Core/Payment/eWAY.php on line 229.

This patch prevents the error message from happening.
