Remove account reporting from Android Omaha client

The profile sign-in state is reported via UMA and can be accessed at
go/chrome-sync-signin (Googlers only, sorry).

The number of Google accounts on the device is no longer relevant, since
Play Store can update Chrome without a Google Account on modern devices.
