tools/javac/processing/T6416433.java is failing on image build.

The problem is that the processor recompiles itself but doesn't
propagate the class path from jtreg (which includes tools.jar).
Consequently, com.sun.source.util and com.sun.tools.javac.api do
not exist.

Furthermore, the test has the wrong name. It should be
T6414633.java, not
T6416433.java
