citgm-all -J doesn't finish and times out with no report

[refack]

• Node Version: master
• CitGM Version: master
• Platform: all

Examples:
https://ci.nodejs.org/job/citgm-smoker/1616/nodes=ppcle-ubuntu1404/console
https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1616/nodes=ubuntu1604-64/console

I thought it might be lerna but excluding it is still stuck:
https://ci.nodejs.org/job/citgm-smoker/1619/nodes=ppcle-ubuntu1404/console
I also extended the timeout to 1200s

I'm now trying excluding downlevel:
https://ci.nodejs.org/job/citgm-smoker/1620/nodes=ppcle-ubuntu1404/console

But it seems like it's a CITGM code issue.

It's probably graceful-fs - https://ci.nodejs.org/job/citgm-smoker/1621/ this job concluded.

Magic incantation: CITGM_COMMAND = citgm-all -J --excludeTags graceful-fs
