Add fuzz inputs

[maflcko]

Done with something like the following to allow for reduced inputs to get added to the repo. C.f. #150 (comment)

mv fuzz_seed_corpus fuzz_inputs_upstream
../bitcoin-core/test/fuzz/test_runner.py -l DEBUG --par $( nproc ) --m_dir ./fuzz_inputs_upstream/  --m_dir ../results_from_working_farm/fuzz_seed_corpus/ --m_dir ../etc/... ./fuzz_seed_corpus
git restore -- ./fuzz_seed_corpus
git add ./fuzz_seed_corpus
git commit -m "Add fuzz inputs"
