Remove leftover diagnostic that dumps generated class from
test/jdk/java/io/Serializable/records/SerialPersistentFieldsTest.java
At one point it was useful to be able to inspect the generated bytecode using
javap, but it was noticed recently for a different reason that the output file
is always R1.class, which is clearly wrong. Anyway, this can simply be removed.
