[MOS-783] Working Pure simulator after partition changes

Fixed iosyscalls so that Pure simulator
works after directory structure changes.

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

    Works:

    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.
