Updates runtimebase-dev.dockerfile to mirror the multi-arch wizardry in runtimebase.dockerfile (perhaps at some point we should implement the same image-stripping stuff in our nitro-cli images so we can drop that from both)
Adds architecture detection to build_local_deps.sh so it automatically works on both x86_64 and aarch64
