Allow other plugins to filter product in WC_Meta_Box_Product_Data::output

The custom WP query in there uses suppress_filters = on by default so it
needs explicit suppress_filters = 0
Two filters for term ids in sales by category reports

This will be used by third parties in order to include additional
products that are included under the selected categories but not
directly.
e.g. in WooCommerce Multilingual this will be used to include the
categories in all languages when building the report hence including
products purchased in any language.
