tools/zlib: update to 1.3.2

Release Notes:
https://github.com/madler/zlib/blob/v1.3.2/ChangeLog

We also switch package tarball source to GitHub repository releases
to avoid package hash mismatch after the zstd upgrade.

The 900-* patch was suppressed by the upstream commit 15ba5055a935
("CMake: Adapt pkgconfig-file to the GnuInstallDirs layout.")
