[LibFuzzer] Declare and use sanitizer functions in ``fuzzer::ExternalFunctions``

This fixes a lot of the linking problems on OSX. Unfortunately it
doesn't fix all of them (some tests have calls to
``_sanitizer_cov_trace_pc_indir`` which we don't define).

This is very much WIP as there are bunch of things that needing doing properly.
