sys-libs/llvm-libunwind: Bump sys-devel/llvm dep for --cmakedir

Require LLVM 4.0 or newer for llvm-config to provide --cmakedir option.
This overrides the fallback CMake directory search done in libdir,
and therefore makes it possible to build the multilib runtime against
a single ABI variant of LLVM.
