    Display encrypted path in the calibration step (#774818)
    
    For an encrypted file system the calibrate step now looks like:
    
        + calibrate /dev/sdb4
            path: /dev/sdb4 (partition)
            start: 6293504
            end: 8390655
            size: 2097152 (1.00 GiB)
            encryption path: /dev/mapper/sdb4_crypt
    
    Bug 774818 - Implement LUKS read-write actions NOT requiring a
                 passphrase
