Fix compiling with separate jsoo mode

[L-as]

It's much faster, but when I try to use it I get this error with a snarkyjs only modified at parts unrelated to this (AFAICT, might be wrong):

[user@nixos:/work/mina/src/lib/snarkyjs/dist/node]$ node

could you show the stack trace when running a script with node --enable-source-maps? this one doesn't help

Node.js v19.8.1

It doesn't really say anything more. I looked at the compiled output, and at some point there is var ..., _s_ = { ..., "port":"" }, and changing the port to "0" instead makes everything work. I am not sure what the code comes from and why it's affected by this.

@mitschabaude Does it work for you locally?

[L-as]

I've added this as a (horrible) work-around to the end of build-snarkyjs-node-artifacts.sh

sed -i 's/"port":""/"port":"0"/' "$BINDINGS_PATH"/snarky_js_node.bc.cjs

[mitschabaude]

Weird stuff! Sorry didn't try locally

A while ago we used separate compilation by default, for the released version of snarkyjs. Moved away from it to get smaller JSOO bundle
