Subject: [PATCH] Update zlib to 1.3.2

Note that the DLL name created by CMake with `BUILD_SHARED_LIBS`
has changed from `zlib1.dll` to `z.dll`. This was caused by the
"Continued rewrite of CMake build [Vollstrecker]" from its
changelog <https://zlib.net/ChangeLog.txt>, and has been reported
in <https://github.com/madler/zlib/issues/1181>.

The MinGW package `libz-mingw-w64-dev` still calls it `libz1.dll`.
