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.
