build: add cmake to wheel-safe packages for pip install

The latest cmake pip package's bundled curl requires OpenSSL 3.0+,
which fails to build from source on Rocky 8 (system OpenSSL 1.1.1).
CMake wheels are self-contained binaries with no ABI dependency on
the custom Python build, so installing from wheel is safe.
