Fix favicon display on the NTP on os x. The favicons get corrupted before they are written to the favicon db, so this patch will only fix new favicons.
Fix favicon display on the NTP on os x. The favicons get corrupted before they are
written to the favicon db, so this patch will only fix new favicons.

TEST=Open the NTP and see that favicons with transparency look broken. Close Chromium, delete ~/Library/Application\ Support/Chromium, go to a page with a favicon with transparency (e.g. http://codereview.chromium.org/), open another NTP, and make sure that the favicon is now displayed correctly.
BUG=None as far as I know.
