This change attempts to make the minimal modifications required in order to have FullscreenController::ToggleFullscreenMode consistently mean fullscreen with no browser chrome on all platforms.

Mac 10.6 bot is consistently having CHECK error here:

[2238:263:0130/035234:4049296547214:FATAL:fullscreen_controller.cc(535)] Check
failed: base::mac::IsOSLionOrLater(). 

Let me try reverting this to see if it fixes. (If it was a false positive I'll
revert this revert)

Hmm this doesn't fix.  Probably I should revert this revert or go on to try
reverting r179399...

Ok, I'll revert this revert as the bot is not a closer. Hope you can fix
the issue when you see this mail.
