[CrOS Extensions] Update Mobile Activation extension to manifest v2

Manifest v1 extensions will no longer be loaded in M67. We need to
update this extension to manifest v2.

Update the manifest, and add a trivial browser test to at ensure the
extension is properly loaded on CrOS (since it looks like we don't have
any other coverage for this).

This should be fixed, and will likely need a merge.  Setting a reminder for Monday to request a merge if all looks good.

I have not tested this against any specific CrOS devices beyond what are running on our trybots and waterfalls, but it should be a reasonably low-risk change.

I'll defer to stevenjb@ for CrOS expertise on whether this should be sufficient, or if there's more we should test.

I suspect the extension is actually unused, but we have not been able to prioritize verifying that. In the meanwhile this change is straightforward and low risk and we should merge it in case the extension API is in fact used (my understanding is that it won't work at all without this change).

Per #9, I'll merge.
