calamares: fix module functionality

[vlinkz]

Motivation for this change

The calamares locale module segfaults and crashes calamares when loaded. When the keyboard module is used, no options are available. Both of these modules were broken due to hardcoded paths pointing to the wrong files. Also, the password quality checking functionality in the users module was missing.

Things done

Changed hardcoded paths to fix the issues in the locale and keyboard modules. Also added libpwquality dependency to enable password quality checking in the users module.

I removed changes that were unnecessary for proper execution of the program. I also added a fix for launching from the desktop.
