Global Build timeout does not work for Multibranch Workflows

### Jenkins and plugins versions report

Environment

### What Operating System are you using (both controller, and any agents involved in the problem)?

5.4.228-132.418.amzn2.x86_64

### Reproduction steps

1. We have set the global time out to Absolute 3 minutes (the minimum available)
2. We ran a multibranch workflow

### Expected Results

Multibranch workflow should be aborted after 3 mins

### Actual Results

The job is never aborted

### Anything else?

I can confirm the timeout works on free style jobs, but not in multibranch
