I've configure a new job https://ci.nodejs.org/job/node-test-commit-custom-suites-freestyle/ (job XML attached).
This should replace https://ci.nodejs.org/job/node-test-commit-custom-suites/ in node-test-commit, as the current one is based on `multijob` which ignores the `PLATFORM_LABEL` parameter, which is unneccecery in this scenario.
Because of its limitations the current job is recursive (the flyweight job runs on a `jenkins-workspace` node and the actual build also runs on a `jenkins-workspace` node) so when the systems under load it can lead to unexpected behavior.

This is the diff from the current job https://www.diffchecker.com/MKqrFehH
