Changed expired password in lightdm does not change eCrypfs password

[Ari Sovijärvi]

In a system with eCryptfs encrypted home directories and expiring user passwords, when a password expires, lightdm correctly asks for a new password but fails to update eCryptfs's passphrase with the new password.

This causes a situation where graphical login fails and the user needs to log in from the text mode console and change the eCryptfs password manually to match the new login password.
