Add GPU support to the local experiment of fuzzbench

Excuse me. I just tried to add GPU support to the container so that I could test my Neural Network-based fuzzer. I have managed to add GPU support in generated.mk and run_experiment.py, and the test on all target program were just passed using command "make test-run-myfuzzer-all". However, when I just started a local experiment using run_experiment.py, the test failed, and the `runner` container seemed just not to add GPU support. Could anyone tell me where the problem might be, and what I could do to continue the experiment? Thanks!

PS: It seemed that the container created by "run_experiment.py" just invoked another container to run the experiment, but I couldn't find where the invoke command is.
