Allow cmake<4 when building libavif and libtiff

[radarhere]

libtiff has started failing to build in main on WIndows - https://github.com/python-pillow/Pillow/actions/runs/14187037544/job/39744130790

This would be due to the recent release of cmake 4 - https://github.com/Kitware/CMake/releases/tag/v4.0.0

https://cmake.org/cmake/help/latest/release/4.0.html#deprecated-and-removed-features

Compatibility with versions of CMake older than 3.5 has been removed.

We still have some libavif failures on Windows:

They mysteriously reverted to the 20250309.1.0 runner image. I reran the jobs and they passed this time.

If you'd like, #8855 adds rustup update to fix the problem even in the earlier runner image.

Thanks! Good to know we can restart it and hopefully get the newer runner.

I'll go ahead with the release without merging it to save a bunch of CI time, but we can merge it afterwards if we see it pop up again.
