Rename libjdwp expectations files.

It was very confusing and difficult to remember which files went with
which test configuration. Hopefully with this rename things will be
clearer.

Test: ./art/tools/run-jdwp-tests.sh --mode=host
Test: ./art/tools/run-libjdwp-tests.sh --mode=host
Test: ./art/tools/run-prebuilt-libjdwp-tests.sh --mode=host
