Revert of Disable UI flags for non-desktop OSes (patchset #4 id:60001 of https://codereview.chromium.org/480453002/)

Reason for revert:
This will cause android to lose account consistency. I should not have removed the file!

Original issue's description:
> Disable UI flags for non-desktop OSes
>
> This is mostly to prevent the high res avatars from being downloaded when not necessary, and will also prevent any other non-UI side effects which are undesired on non-desktop OSes.
