Move //libdeno to //core/libdeno (#2015)
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.
