kunit: add tests for using current KUnit test field 

Create test suite called "kunit_current" to add test coverage for the use
of current->kunit_test, which returns the current KUnit test.

Add two test cases:
- kunit_current_test to test current->kunit_test and the method
  kunit_get_current_test(), which utilizes current->kunit_test.

- kunit_current_fail_test to test the method
  kunit_fail_current_test(), which utilizes current->kunit_test.
