Fix jacoco_cli invocation

Browse Source 
jacoco_cli --dest takes a directory, not a jar name, and assumes
an output file with the same name as the input jar in that
directory.  Rename jacoco-report-classes.jar to
jacoco-report-classes/modulename.jar, and generate to
jacoco/tmp/modulename.jar before combining to the final output file
at jacoco/modulename.jar.
