[6/9] selftets/damon: prepare for monitor_on file renaming

Commit Message

SeongJae Park Jan. 30, 2024, 1:35 a.m. UTC

Following change will rename 'monitor_on' DAMON debugfs file to
'monitor_on_DEPRECATED', to make the deprecation unignorable in runtime.
Since it could make DAMON selftests fail and disturb future bisects,
update DAMON selftests to support the change.
