The rdf:types in DBpedia are based on the template to ontology mappings which are maintained in the mappings wiki (http://mappings.dbpedia.org). As of DBpedia 3.5 the "Infobox former country" template is mapped to the ontology class Country. E.g. the SFR Yugoslavia (http://en.wikipedia.org/wiki/Socialist_Federal_Republic_of_Yugoslavia) has been a country once, that is a fact. So if you want to filter current countries you might want to check whether they don't have a dissolution year (http://dbpedia.org/ontology/dissolutionYear) for example. The "former" fact might be useful to be added as a triple in the future, but the ontology class should remain Country in my opinion.
