Romain Naour c43f12293d package/rustc: rust >= 1.73.0 needs cmake >= 3.20 
The bump to rust 1.74.1 [1] introduced a regression on host using
cmake < 3.20 since the llvm libraries used in rust compiler was
bumpted to llvm 17 [2] and now requires cmake >= 3.20 [3].

Select BR2_HOST_CMAKE_AT_LEAST_3_20 to build host-cmake when needed.
