bug#35540: Installer displays encrypted partition password entry in cleartext

[pelzflorian (Florian Pelz)]

When creating an encrypted partition in Manual partitioning (maybe
also Guided?) in the Newt installer, it asks for a password with which
to encrypt the partition.  However only the password confirmation
password entry diplays ******* instead of the typed password, the
password entry before displays the password in cleartext.
