Fix a race detected only if a test times out #3808

I believe this can happen because the goroutine is started before the command is started. Start the process first, then on success, start the signal handler. Add a test for regression.

I verified the test fails without my change to wrap.go and the race is from the signal handling goroutine.

What type of PR is this?

Bug fix

What does this PR do? Why is it needed?

It prevents a race detection when a test is timed out. We saw this a bunch and devs were really confused thinking there was a legit race detected.

Which issues(s) does this PR fix?

@patrickmscott Thanks for catching this. I'm still not sure I understand why there is a race in the first place. Could you post the race detector trace you see?

Nevermind, this makes sense, I missed that we are accessing Process on cmd.
