This removes the 'keep' option from the download notifications for known malware (dangerous host, URL, or content).

Windows, ChromeOS: This removes the 'keep' option from the dropdown menu that hangs off the notification/warning. Only the 'learn more' option remains in the dropdown menu that hangs off the notification. One exception: mattm is doing a feedback experiment, and if that experiment is turned on there is also a plain 'discard' option in the shelf.

GTK (Mac, Linux): This removes the 'keep' option from the main download notification itself, since there is no dropdown. 

This does *not* change anything in chrome://downloads.
