binder_rpc_fuzzer: add corpus entry

Custom corpus entry to execute a special transaction. The coverage
guided fuzzer wasn't making very much progress, because it needed to
guess the wire protocol version and also the connection init string
('cci').

Corpus file created with:

    echo "000000F0000000000000000000000000636369000000000000000000280000001111111111111111000000000000000000000000000000000000000000000000000000000000000000000000000000008d4a8d4a" | xxd -ps -r
