Fix building for Cloudflare Nitro preset (#1726)

It seems that Rollup node-resolve module doesn't properly deal with
trailing slashes, causing it to thing that `string_decoder` is a
built-in Node.js dependency and attempt to import it from `unenv`, which
will obviously fail, because `string_decoder` is not, in fact, a Node.js
dependency, but an individual dependency of `readable-stream`.

This adds a small patch for `readable-stream@2.3.8` dependency, which
removes the leading slash, which seems to fix the builds.

This probably should be reported to relevant developers (Rollup
node-resolve plugin or Nitro?).
