lockdep/selftest: Add more recursive read related test cases
Add those four test cases:
1. X --(ER)--> Y --(ER)--> Z --(ER)--> X is deadlock.
2. X --(EN)--> Y --(SR)--> Z --(ER)--> X is deadlock.
3. X --(EN)--> Y --(SR)--> Z --(SN)--> X is not deadlock.
4. X --(ER)--> Y --(SR)--> Z --(EN)--> X is not deadlock.
Those self testcases are valuable for the development of supporting
recursive read related deadlock detection.
