llhttp: Adding a comment to template
I only added a comment to the template saying that nodejs and nodejs-lts need to be updated/rebuilt when llhttp is updated.  I did not increment the revision since no rebuild is needed for this.

A patch file from https://github.com/void-linux/void-packages/pull/21921.patch is attached
