[gparted] Also prompt for LUKS password as required for check operation (#59)

    Also prompt for LUKS password as required for check operation (#59)
    
    A check operation involves (1) checking the file system, (2) growing the
    encryption volume and (3) growing the file system.  Therefore prompt for
    the LUKS passphrase as required when composing a check operation too.
    
    Closes #59 - Resize of LUKS2 encrypted file system fails with "Nothing
                 to read on input"
