fix(package-tiff): wire zlib into libtiff so the Deflate codec is built

libtiff already declared zlib as a dependency, so it was fetched and built, but the CMake flags were never passed through — every published build (up to beta.24) shipped libtiff without Deflate/zip support. Forward -Dzlib=ON and the ZLIB_* paths via ifDep, matching the existing jpeg/lerc/zstd wiring.
