Subject: [PATCH 05/10] selftests/damon: classify tests for functionalities and regressions

DAMON selftests can be classified into two categories: functionalities
and regressions.  Functionality tests are for checking if the function
is working as specified, while the regression tests are basically
reproducers of previously reported and fixed bugs.  The tests of the
categories are mixed in the selftests Makefile.  Separate those for
easier understanding of the types of tests.
