Subject: [PATCH] Suppress stdout output for fuzzers in projects/orbit (#6909)

We recently added a new fuzzer that prints a lot to stdout due to
how error messages are handled. With this change we suppress this
output.

The understanding is that useful output from asan, etc. goes to
stderr, which we do not suppress.
