function _upload_element_add_file_validators in Upload element 6

This is used to set the default validators

We are in a catch-22 here. If we set it in hook_elements, the chances are that these will be overridden by any user defined values. If we set these in the #process callback, the options are not available to form_type_"hook"_value or theme functions.

As such, we dynamically add these here.
