chrome.experimental.identity is only around for a couple of apps that got
permission to use the API in order to launch before chrome.identity.

Unless there's some reason, we should be doing everything for Kiosk on
chrome.identity, and leave the experimental API as is.

OK, reverted the experimental changes.
