Target: serverless still required react, react-dom to be installed

Bug report

Describe the bug

next start a serverless build, still prompt me the error that require 'react', 'react-dom'.

I thought the React is inlined with the output, isn't it?

[timneutkens]

It's inlined in the bundle indeed.

You shouldn't use next start to production host the serverless target, it's not optimized to run everything as a single "server" instead the bundles should be wrapped and served separately

[grepug]

I was trying to deploy the serverless build to AliCloud which has its own implementation for Serverless where res and req objects are slightly different with next's output.

Am I supposed to write a custom server to hook them up? or any good idea?
