Add fuzzing support to build system
LibFuzzer, Honggfuzz and other programs implement simple interfaces for
fuzzing appropriately prepared code. Samba contains quite a lot of
parsing code, often a good target for fuzzing.
With this change the build system is amended to support building fuzzing
binaries (added in later changes).
