node comapt: Deno.openSync shim seems to fail

[sigmaSd]

I have a package that uses dnt to build to npm, dnt locally works and pass all the tests

But If import the published package it fails with

error: Uncaught (in promise) Error: OpenOptions requires at least one option to be true
    at checkOpenOptions (ext:deno_fs/30_fs.js:681:11)
    at Object.openSync (ext:deno_fs/30_fs.js:560:16)
    at openSync (ext:deno_node/_fs/_fs_open.ts:98:15)
    at Object.openSync (file:///home/mrcool/.cache/deno/npm/registry.npmjs.org/@deno/shim-deno/0.16.1/dist/deno/stable/functions/openSync.js:25:38)
    at Module.getFromPath (file:///home/mrcool/.cache/deno/npm/registry.npmjs.org/deno-infer/1.0.6/esm/mod.js:56:31)
    at file:///home/mrcool/dev/deno/denoseal/main.ts:16:21

I added some debug statements, and openSync in deno shim does pass O_READONLY (which seems to be encoded as 0) to deno_node

To reproduce:

import * as infer from "npm:deno-infer@1.0.7";
const type = infer.getFromPath("/usr/bin/ls");

The code for that version is here https://github.com/sigmaSd/deno-infer/tree/80c3c8b4861386701a4b714f8d59ff224577a6a6
