Update {virtual,override} to follow C++11 style in ui.

Update {virtual,override} to follow C++11 style in ui.

The Google style guide states that only one of {virtual,override,final} should be used for each declaration, since override implies virtual and final implies both virtual and override.

avi: please look at this boring patch

Nothing against Avi as reviewer, but shouldn't you send this (ui/) to either
Scott (sky) or Sadrul?

That's the problem with comments in OWNER files. I'm in there as a Mac owner,
but that restriction is only in a comment, so the tooling doesn't notice.

For something mechanical like this, I'm capable of evaluating this just as well
as the other general owners, plus I'm on his team so he's familiar with me. I'm
OK with this.

LGTM for the change; boring change is boring.

Thanks for commenting about this Thiago -- I hadn't noticed the owners file
comment (was just trusting the Chromite Butler extension) and sent it to Avi
since he and I have been working closely together on other stuff. I wonder how
hard it would be to update the extension to show the relevant annotations.
