Cedar: Add "BLAKE2" submodule

OpenSSL provides BLAKE2s, but it only supports an output of 32 bytes. For WireGuard we need a 16 bytes output as well.

The minimum CMake version is bumped to 3.10 because it adds HAS_SSE2 to cmake_host_system_information(): https://cmake.org/cmake/help/v3.10/command/cmake_host_system_information.html
