selftests/damon: add a test for a race between target_ids_read() and dbgfs_before_terminate() commit 34796417964b ("mm/damon/dbgfs: protect targets destructions with kdamond_lock") fixed a race of DAMON debugfs interface. Specifically, the race was happening between target_ids_read() and dbgfs_before_terminate(). Add a test for the issue to prevent the problem from accidentally recurring.
