Revert of analyze: ignore changes to OWNERS files (patchset #2 id:20001 of https://codereview.chromium.org/2117363002/ )

Reason for revert:
reverting this since I don't think it should've been needed and I'd like to look at the problem further. I will re-land or fix as appropriate if I can reproduce the underlying bug.
