[Extensions] Update miscellaneous 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 miscellaneous manifest files under
chrome/test/data/extensions/ that weren't named manifest.json and
weren't in a subdirectory to warrant updating them all in a patch.
All files updated cleanly.
