test: fix flaky test-https-timeout
Browse files Browse the repository at this point in the history
Remove `setTimeout()` in test and instead rely on `common.mustCall()` on
a `timeout` event handler.

The test was flaky on CI. The flakiness was replicable by running the
test under load. This version, in contrast, is robust under load.

Took the opportunity to do some `var` -> `const` while refactoring.
