Allow opening an AEC dump from an existing file handle.
This is necessary for Chromium to be able enable the dump with the sanbox enabled. It will open the file in the browser process and pass the handle to the render process. This changes FileWrapper to deal with the case were the file handle is not managed by the wrapper.
