When building against zlib-ng, the header file `zlib.h` is not included, but `zlib-ng.h` is included instead. It's `zlib.h` that defines `ZLIB_VERSION` and that macro is used to print out zlib version in `git-version(1)` with `--build-options`. But when it's not defined, no version is printed. `zlib-ng.h` defines another macro: `ZLIBNG_VERSION`. Use that macro to print the zlib-ng version in `git version --build-options` when it's set. Otherwise fallback to `ZLIB_VERSION`.
