Anton Protopopov 90c22503cd selftest/bpf/benchs: Make quiet option common
The "local-storage-tasks-trace" benchmark has a `--quiet` option. Move it to
the list of common options, so that the main code and other benchmarks can use
(new) env.quiet variable. Patch the run_bench_local_storage_rcu_tasks_trace.sh
helper script accordingly.
