Fix issue with custom option file uploading

[nikolaevas]

Description (*)

If sys_temp_dir and upload_tmp_dir directives in php.ini are different then it causes exception when uploading a file to product custom options on the frontend:

Path "%1" cannot be used with directory "%2"

Manual testing scenarios (*)

1. Set different values for sys_temp_dir and upload_tmp_dir in php.ini.
2. In magento create simple, visible in catalog product.
3. Add new customizable option to that product with option type File.
4. On product page on frontend select file for custom option and press Add to cart button.
