    Simplify XFS copy specific code progress bar usage (#760709)
    
    Remove starting and stopping the progress bar in xfs::copy().  The
    progress bar will be automatically started in xfs::copy_progress()
    callback when run_progressbar() is called; and automatically stopped in
    FileSystem::execute_command() when it calls stop_progress() at the end.
    
    Note that this will now not initialise the progress bar from zero
    immediately that the XFS copy is started, but instead 0.5 seconds into
    the copy when xfs::copy_progress() timed callback is called for the
    first time.
    
    Bug 760709 - Add progress bars to XFS and EXT2/3/4 file system specific
                 copy methods
