backends/Dialog: Add support for output handling
dialog(1) uses stdin to display the dialog boxes and prints output to stderr (if applicable). This patch changes the command invocation in the Dialog backend to capture stderr. stdin and stdout are inherited from the main process so that dialog can display the dialog boxes and receive user input.
