Review Request: 8007524: build-infra: Incremental build of tools.jar broken

[Erik Joelsson]

The logic for setting up correct dependencies from class files to jar 
files in the macro SetupArchive is broken. This fixes two things. The 
wrong variable was used to filter files found and a ',' was missing in 
the macro call to CacheFind. Verifed that dependency list is now 
populated instead of empty as before, and that changing a class in javac 
caused tools.jar to be updated.
