sensor build fails on ppc64l and aarch64

[mmaslano]

esbuild depends on architecture. We need to either change magefile.go to call "npm ci" or install esbuild-wasm with much worse performance.

(It doesn't have priority right now, just tracking it).

I think for now we only need the server on x86_64 which is building. We need the clients for ppc64l and aarch64 and they are building too.
