Summary
Related to #5304. I didn't test it well enough. That change worked with a globally installed jest-cli and a local installation of jest-cli. It did not work for a global jest install and a local jest install if jest-cli is within node_modules/jest/jest-cli instead of at the top level.

This change fixes that.

(I want to point out that the original code before #5304 didn't work in the same case (as it hardcoded a node_modules/jest-cli path) - and why I think so many projects have both jest and jest-cli in their dependencies.)

Test plan
Local testing with a globally installed jest (with this change applied) and a local node_modules/jest/jest-cli installation.

Dang, I thought about this but thought it would work because jest just goes to jest-cli, but I guess it's requiring the wrong version of jest-cli…

It worked if jest-cli was hoisted to the top level, which is not necessarily the case.
