fixup! [M47_2516] Chromium upversion to m47_2516 branch

We have following dependency:
chrome_resources.gyp:packed_resources
-> extensions/renderer/resources/extensions_renderer_resources.grd
-> ${mojom_root}/chrome\browser\media\router\media_router.mojom.js

The build breaks because of missing media_router.mojom.js, which is
expected to be auto-generated but not in our case. So, patch adds a
gyp dependency to generate the file, and removes the corresponding
patch file which was added temporarily to bypass the issue.
