`--no-dictionaries` flag seems to be ignored by some fuzzers/benchmarks.

[Marco Vanotti]

It seems like some fuzzer-benchmarks combinations do not respect the --no-dictionaries option.

For example:

aflplusplus and libpcap_fuzz_both

in my experiment config I have:

no_dictionaries: true

But in the fuzzer logs I see:

[run_afl_fuzz] Running command: ./afl-fuzz -i /out/seeds -o /out/corpus -m none -t 1000+ -d -x ./afl++.dict -c /out/cmplog/fuzz_both -- /out/fuzz_both 2147483647
