Make run-jdwp-tests.sh warn about deprecation

Since the internal jdwp implementation is deprecated when running the
JDWP test suite one should generally use ./tools/run-libjdwp-tests.sh
instead of ./tools/run-jdwp-tests.sh. This makes run-jdwp-tests.sh
require a special flag to run if not invoked through
run-libjdwp-tests.sh or by LUCI. This should help ensure people run
the appropriate tests.

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