[MOS-783] First part of new dir structure implementation

    Works:
    - generating .img for Pure;
    - Pure boots after flashing new image and
    seems to be working fine;

    Not yet:
    - generating update package;
    - generating image for Harmony;
    - simulator;
    - path-related unit tests fail
    due to paths being hardcoded
    in test scenarios.

* Added script to generate scripts package
automatically
* Added integration with PureOS CMake

disconnected.

Additionally minor code cleanup.

[CP-1579] Fix correct password inserted during Pure boot is not accepted

Fix the issue when the USB cable connected to the device during boot up
and Center requested a passcode before the device was fully up.
What caused a 'Wrong passcode' message after typing a passcode
