    math/heyoka: fix build against devel/llvm18 and higher
    
    When building with DEFAULT_VERSIONS+=llvm=18 or higher, math/heyoke
    fails to configure, with the following error:
    
      CMake Error at CMakeLists.txt:159 (find_package):
        Could not find a configuration file for package "LLVM" that is compatible
        with requested version "18".
    
        The following configuration files were considered but not accepted:
    
          /usr/local/llvm15/lib/cmake/llvm/LLVMConfig.cmake, version: 15.0.7
          /usr/local/llvm17/lib/cmake/llvm/LLVMConfig.cmake, version: 17.0.6
          /usr/local/llvm16/lib/cmake/llvm/LLVMConfig.cmake, version: 16.0.6
          /usr/local/llvm18/lib/cmake/llvm/LLVMConfig.cmake, version: 18.1.8
    
    This is because llvm18 and higher use 1 for their minor version numbers,
    while llvm17 and earlier use 0. CMake's find_package() needs the minor
    version number set correctly, otherwise it will not be able to find the
    LLVM package.
