I think making this OS_CHROMEOS only will break, because the extension API code
will try to read the pref also for non-OS_CHROMEOS configurations. Have you
tested on a desktop build?

That brings up the question of how to handle desktop builds :) Either ifdef
OS_CHROMEOS in the extension API (but that seems weird) or move the pref
registration somewhere else...

Updated to make profile pref always present, and local state  OS_CHROMEOS
guarded. Not sure it's the best approach though.
