Fix JvmRuntimeDescriptorLoaderTestGenerated

- Use FULL_JDK instead of mock JDK in some tests because mock JDK is
  created from JDK 6 and full JDK is now JDK 8, so there are differences
  in the behavior in the compiler and at runtime
- Remove some '*.runtime.txt' files which were workarounds to JDK 6
  reflection issues regarding generic inner classes; code in these tests
  is now loaded exactly the same in the compiler and at runtime
- Change supertype in SupertypesAndBounds.kt: the class in the supertype
  is not relevant to that test, it checks that annotations can be loaded
  on types
