Bug 1637703 [wpt PR 23573] - [ResourceTiming] Fix flaky test, a=testonly

Automatic update from web-platform-tests
[ResourceTiming] Fix flaky test

Looks like the recent change to status-codes-create-entry.html made it
flaky, so this CL undos that. It also removes the analogous check in the
new test cross-origin-status-codes.html.
