[0/9] misc fixups for DAMON {self,kunit} tests

This patchset is for minor fixups of DAMON selftests and kunit tests.
First three patches make DAMON selftests more cleanly maintained
(patches 1 and 2) without unnecessary warnings (patch 3).  Following six
patches remove unnecessary test case (patch 4), handle configs
combinations that can make tests fail (patches 5-7), reorganize the test
files following the new guideline (patch 8), and add reference
kunitconfig for DAMON kunit tests (patch 9).
