progressbar: Don't explicitly signal SIGUSR1 anymore

If the progressbar thread hits an unrecoverable error then
exit via BAD_ERROR rather than explicitly raising
SIGUSR1, as BAD_ERROR now does the right thing (it
itself raises SIGUSR1 and kills the calling thread if apppending,
or just exits itself if not appending).
