Locate build history when file is outside of root project dir

Support use-cases when the build dir is outside of root project dir.
Many projects set up output dir as <root_project>/../out/<project_name>/build
to be able to clean build dir more easily. This commit adds support
to build history file detection and it tries to find build history
files for artifacts that are:
- under root project dir (a default structure)
- under root project's build dir parent (to support typical custom setup)
