Fixes some sed errors introduced in c43cfe. Unfortunately moving libdeno required splitting build.rs into two parts, one for cli and one for core. I've also removed the arm64 build - it's complicating things at this re-org and we're not even testing it. I need to swing back to it and get tools/test.py running for it.
