…ut failures

What's the problem this PR addresses?

In order to pass citgm, we need to suppress timeout failures. See the discussion thread nodejs/citgm#905 (comment)

How did you fix it?

To add env variable TEST_IGNORE_TIMEOUT_FAILURES to turn on this kind of suppression

I would rather we try to figure out why the timeouts happen, if Node.js introduces changes that causes timeouts they wont be caught with this.

@merceyz I think the priority is to get CITGM to work with Yarn in its current state, as most of the problems will be caught even without catching timeouts (regressions, empty event loops, ... the process hanging for real is possible, but only one very unlikely symptoms amongst many).

Additionally, debugging it on their infra seems a real pain as tests have to be run manually by someone else, so it's hard to estimate how long it'd take to find the problem, and is probably out-of-scope for a first-time contribution.

[merceyz]

@arcanis That's fair, I retract my objection.

I've triggered a release for this, should be ready soon.
