Update config=sanitize and fuzz targets

We used to need to silence float-divide-by-zero and float-cast-overflow sanitizers since clang used a finite valid floating point value range. Fortunately, since clang-9 UBSAN properly handles various primitive operations per IEEE-754 so we no longer need this workaround. Also use fork=16 mode for fuzz targets to make it easier to run fuzzing locally.
