chzcrypt: Corrected handling of insufficient permissions.

Browse Source 
The -d and -e options did not show any failure message when
executed with insufficient permissions (e.g. not root user).
Now the behaviour is equal to the other options: A message
'chzcrypt: Error - can't write to xxx. Wrong permissions or
wrong tools version' is printed.
