Don't show temporary file names in title bars.

For dialogs and auxiliary windows, if we have a live capture that hasn't
yet been saved to a permanent location, there's no good reason to show
the temporary file name in the title bar, as:

  it's a random string that doesn't indicate where the capture was done
  and that could confuse people (see, for example, the confusion in bug
  14929, in which somebody referred to the "Follow TCP Stream" window as
  the ".pcap dialog" because its title had ".pcap" at the end, due to
  the capture file being a temporary file and its name showing up in the
  title bar of that window);

  it differs from what the main window title bar shows.

While we're at it, don't assume that the file name in the capture_file
structure is a UTF-8 string - some UN*Xes might not use UTF-8 for file
names.
