Subject: [PATCH] build: fix duplicate OS_CODE definitions on macOS

`TARGET_OS_MAC` and `__APPLE__` are both true on macOS, which results in

duplicate definitions for `OS_CODE`.

Upstream removed the check for `TARGET_OS_MAC`, as well as the ancient

compat code, in

https://github.com/madler/zlib/commit/4bd9a71f3539b5ce47f0c67ab5e01f3196dc8ef9.

This was fixed in varnish >= 7.6 as part of https://github.com/varnishcache/varnish-cache/commit/86df12b6c1ad8208899ea353fdcbea227356fcf8.
