Build libFuzzer from source
Building libFuzzer from source is easy and has multiple advantages:
* The clang distributed with XCode on macOS does not include libFuzzer.
* Applying a small patch to libFuzzer will allow us to replace the
--wrap linker feature, which is not supported on platforms other than
Linux.
