[ghex] Assume the file chooser never returns directory name when asked for a file name

    Assume the file chooser never returns directory name when asked for a file name
    
    In GTK_FILE_CHOOSER_ACTION_SAVE mode, GtkFileChooser doesn't let the
    user accidentally pick a directory instead of a file name.
    
    Getting rid of the unneeded directory handling code rids us of some more
    code that operated under the assumption that / is always the directory
    separator.
