commit 949caef9e2835f21783eb371a64e0658cf35f256
Author: Alexander Kanavin <alexander.kanavin at linux.intel.com>

    package_manager.py: move postinst_intercept dir initialization from RootFS to PackageManager class
    
    This will allow handling postinst_intercepts when populating SDKs (which
    use PackageManager class directly, and do not utilize RootFS class).
