Fuzzer: Fix library dependencies.

Newer versions of libstdc++ (4.9+), as well as libc++, depend directly on
libpthread from the standard library headers, so libfuzzer needs to declare

[libFuzzer]Add a test for defeating a hash sum.
...
Summary:
Add a test for a data followed by 4-byte hash value.
I use a slightly modified Jenkins hash function,
as described in https://en.wikipedia.org/wiki/Jenkins_hash_function
The modification is to ensure that hash(zeros) != 0.
