Pull request: test: fix flaky debugger test

For some reason, I’ve lost Jenkins permissions and can’t post the detailed URL, but I’m modifying the contents of this CI:
https://ci.nodejs.org/job/node-test-commit/79774/

I encountered this on my Windows machine when running this command.
``` sh
 python3 tools/test.py --repeat=10000 parallel/test-debugger-break
```

https://github.com/nodejs/node/blob/b1973550e09d5a2a07c70be5de6e3ae4722ad230/test/parallel/test-debugger-break.js#L37-L44

The cause was the output of the cont command.
Normally, it looks like this

``` sh
< Hello Robin
< 
break in test/fixtures/debugger/break.js:10
  8 }
  9 sayHello();
>10 debugger;
 11 setTimeout(sayHello, 10);
 12 
debug> 
```

However, on rare occasions, the order of the debugger output and standard output is reversed like this:

``` sh
break in test/fixtures/debugger/break.js:10
  8 }
  9 sayHello();
>10 debugger;
 11 setTimeout(sayHello, 10);
 12 
debug> 
< Hello Robin
< 
debug> 
```
So I modified it to wait for the corresponding response before proceeding to the next command.
