build timeout does not propagate as timeout

[PLukas2018]

We have timeout when building kernel

diffkemp-dev-bot/src/container.ts

Line 74 in bc65066

timeout: options?.timeout,

the timeout ends the command in the container but it is not propagated as error/timeout to nodejs and it is taken as success.

Reproducer:

/* reproducer.js */
import { execFile, execSync } from "child_process";                             
import { join } from "path";                                                    
import { promisify } from "util";                                               
                                                                                
const execFilePromisify = promisify(execFile);                                  
                                                                                
try {                                                                           
  const { stdout, stderr } = await execFilePromisify(                           
    "podman",                                                                   
    ["exec", "-ti", "<container-id>", "bash", "-c", "sleep 50000; echo a"],       
    {                                                                           
      encoding: "utf-8",                                                        
      timeout: 1000,                                                            
    },                                                                          
  );                                                                            
  console.error("ok");                                                          
  console.error(stdout, stderr);                                                
} catch (e) {                                                                   
  console.error("error");                                                       
  console.error(e);                                                             
}

$ node reproducer.js
ok

I think this could be solved by using directly timeout command which should take care that we get error to node.
