[Extensions] Update permissions tests to manifest v2

We should (finally) remove support for manifest v1. One of the last
significant dependencies is that a lot of our tests aren't manifest v2
yet.

This CL updates manifest files under
chrome/test/data/extensions/permissions (which are not usually
named manifest.json). All files updated cleanly.
