Be explicit on the modules that are expected to be found and add an
appropriate assertion failure message to help debug when the list
changes.

Fixes: #23884

This is a draft because I highly suspect it will fail --without-ssl and --without-intl builds and I won't be able to work on this further until after the weekend.

The list(s) of modules are what is currently there at the moment (basically I kept running with and without worker threads and added the modules shown in the assertion failure message until the test passed).

(As an aside I found the default assert.deepStrictEqual() message unhelpful for sets because it didn't show all the differences in one go.)

Pushed a small fixup. New CI is yellow: https://ci.nodejs.org/job/node-test-pull-request/21416/

This should be good to go, pending reviews.

Forced pushed to fix after recent changes (#26523 and #26513 (not shown below as Travis doesn't run coverage)) changed the list:

Note that #26523 actually reduced the number of modules loaded (🎉), but didn't reduce the count in the version of test-bootstrap-modules.js prior to this PR.

Sorry, I was reprovisioning a smartos17 machine when this was running. Submitted a resume @ https://ci.nodejs.org/job/node-test-commit-smartos/24405/

New CI: https://ci.nodejs.org/job/node-test-pull-request/21512/ (✔️)

Could I get another review? This test is obviously sensitive to bootstrap refactorings that have been going on and I have had to adjust the lists of modules in the test twice now as other PRs have landed (arguably those PRs should have been adjusting the test with or without the changes in this PR as they affected which modules are loaded by the bootstrap process).
