util.prosodyctl.check: Fix error where hostname can't be turned into A label Where gethostname or tohostname returns an invalid name, e.g. containing underscores or something, to_ascii would reject this and return nil, which triggers an error in the dns lookup. Reported by prova2 in the chat, for whom tohostname returned a long name containing underscores.
