Make plymouth play nice with current ctypt code, part 2.

The reason this works is that inst will refuse to overwrite a file that
already exists.  We jsut make plymouth's code to ask for a password have the
same name as 90crypt's password asking script, and it will override 90crypt's
script while leaving everything else intact.
