[ChromeOS] WebUILoginView returns true for IsPopupOrPanel.

This makes WebUILoginView not a drag-n-drop target as TabContents::ShouldAcceptDragAndDrop would return false now. Besides, WebUILoginView is popup in some sense.

BUG=chromium-os:18781
TEST=Verify crash no longer happens for chromium-os:18781.
