Subject: [PATCH] Restore the `URL.createObjectURL` check to the
 `createObjectURL` utility function (issue 8344)

This is a regression from commit https://github.com/mozilla/pdf.js/commit/3888a993b125e22fdfffd36bf603baf830e6fbe2.

It turns out the even though we have a `URL` polyfill, it's still dependent on the existence of native `URL.{createObjectURL, revokeObjectURL}` functions.
Since no such thing exists in Node.js, our `createObjectURL` utility function breaks there.
