Fix KHR-GLES dEQP test paths. Our GN was using the incorrect path for the new test sets. This was showing up as an isolate_tests failure when running the new tests. Also fixes incorrect search paths for the case list directory when used in a Chromium checkout. And adds a few other missing data dependencies.
