8351319: AOT cache support for custom class loaders broken since JDK-8348426

[iklam]

Since JDK-8348426 (Generate binary file for -XX:AOTMode=record -XX:AOTConfiguration=file), the AOT cache no longer contains classes intended for custom class loaders (these are called "unregistered classes" in CDS terminology).

The fix is simple -- we already remember the set of unregistered classes in the AOT configuration file. We just need to add them into the final AOT cache (see changes in finalImageRecipes.cpp).
