Reland allow JUnit3/4 tests within the same apk to be run by test_runner

This CL change instrumentation_test_instance and other part of the
test_runner script to embed the information whether a test class is
junit3 or junit4. The confirmation mechanism is to check whether the
class's direct parent is java.lang.Object. In junit3, all tests are
decesdends from TestCase, while in junit4, all tests are suppose to be
atomic (extends from Object)
