selftests/damon: split test cases
Currently, the single test program, debugfs.sh, contains all test cases for DAMON. When one of the cases fails, finding which case is failed from the test log is not so easy, and all remaining tests will be skipped. To improve the situation, this commit splits the single program into small test programs having their own names.
