pkg/subsystem: disambiguate subsystems by reproducers
There are some minor subsystems (e.g. PAGE CACHE in Linux) that are
parts of several big subsystems. At the same time, a reproducer can
clearly disambiguate such case.
If subsystems from reproducers and subsystems from guilty files
intersect, only proceed with the results of the intersection.
