Partially fix Java interop for emitted inner classes

The backend uses `rawname` to define the "inner name" of an InnerClass
entry in a classfile, this should be the simple name of the class before
any mangling takes place.

Fixing this allows Java code to reference dotty inner classes, except if
they're defined in objects which is still broken until
https://github.com/DarkDimius/scala/pull/4 is merged and a new backend
is published.
