Revert of Adding Presubmit error when OVERRIDE and FINAL is not used as C++11 standard

Revert of Adding Presubmit error when OVERRIDE and FINAL is not used as C++11 standard (patchset #3 id:40001 of https://codereview.chromium.org/638663003/)

Reason for revert:
The if statement is incorrect. `if 'override' or 'final' in line` === `if 'override'`, because string constants are always true. This means that no one can upload patches, which is a bit annoying.

Please fix in a subsequent patch.

I am extremely sorry for this mistake, I have checked lots of unit tests
scenarios with with respect to Upper case, I'll fine tune my patch and re-check
with many more scenarios and re-submit the patch.

My Apologies to Mr. Avi and Mr. Mike.

This patch, I think, would be fine as `if ' OVERRIDE' in line or ' FINAL' in
line:`.

Actually, I take that back; you'll need to account for things like constants or
enums named "OVERRIDE_SOMETHING_SOMETHING".
