mm/damon/sysfs-schemes: commit filters in {core,ops}_filters directories

Connect user inputs for files under core_filters and ops_filters with
DAMON, so that the files can really function.  Becasuse {core,ops}_filters
are easier to be managed in terms of expecting filters evaluation order,
add filters in {core,ops}_filters before 'filters' directory.
