depends: Fix build of Qt for 32-bit platforms
The 32 to 64-bit time_t transition causes a build failure in the built-in
zlib about conflicting _TIME_BITS and _FILE_OFFSET_BITS.
Note that zlib doesn't use time_t at all, so it is a false alarm.
Take the following patch from upstream zlib:
https://github.com/madler/zlib/commit/a566e156b3fa07b566ddbf6801b517a9dba04fa3.patch
Closes #29980.
Github-Pull: #29985
