We should run WPT lint as part of our own listing infrastructure to ensure exports to WPT don't run into issues that would have been easily addressed ahead-of-time.

Naively, it seems like check-webkit-style would be the right place for this.
We currently are meant to blanket ignore everything in LayoutTests (but see Bug 274407), so this also implies changing the current ignore rule to run a specific lint on a bunch of LayoutTests.
