JDWP: nestedtypes should not include anonymous classes

The naming of these classes cannot be depended on, so any classname that
contains a $[1-9] for now will not be listed. It's name doesn't include
the full scope of what nesting it's in.

Also see 4921247 for the ultimate answer. But the question for the
debugger is, why would you ever want to list these classes?
