compat/zlib: provide `deflateBound()` shim centrally
The `deflateBound()` function has only been introduced with zlib 1.2.0.
When linking against a zlib version older than that we thus provide our
own compatibility shim. Move this shim into "compat/zlib.h" so that we
can adapt it based on whether or not we use zlib-ng in a subsequent
commit.
