Please take a look at section 12.6.4.4 in ISO-32000-1 (that is the PDF specification). That section is titled "Embedded Go-To Actions":

As you've found out, the behavior you describe is by specification. The GoToE action is for jumping to and form a PDF file that is embedded in another PDF file. Other document formats aren't supported because.

Your only option is to introduce a file attachment annotation instead of an Embedded file along with a GoToE action. See for instance the FileAttachmentAnnot example:

public void createPdf(String dest) throws IOException, DocumentException {
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(dest));
    document.open();
    Rectangle rect = new Rectangle(36, 700, 136, 800);
    PdfFileSpecification fs = PdfFileSpecification.fileEmbedded(
            writer, PATH, "test.docx", null);
    PdfAnnotation attachment =
            PdfAnnotation.createFileAttachment(writer, rect, "Click me" , fs);
    PdfAppearance app = writer.getDirectContent().createAppearance(100, 100);
    Image img = Image.getInstance(IMG);
    img.scaleAbsolute(100, 100);
    img.setAbsolutePosition(0, 0);
    app.addImage(img);
    attachment.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, app);
    writer.addAnnotation(attachment);
    document.close();
}

In this example, we create a PdfAnnotation and we define a custom appearance for this annotation (instead of the pin or the paperclip symbol). I used an image because that's what you seem to want. Check out the result here (this works with Adobe Reader, but not all PDF viewers support this).
