Suppress NEW_NAVIGATION_ENTRY prerenderer failures for ORIGIN_OFFLINE

Suppress NEW_NAVIGATION_ENTRY prerenderer failures for ORIGIN_OFFLINE

We have noticed some FINAL_STATUS_NEW_NAVIGATION_ENTRY failures in UMA
for offline pages but didn't know how to trigger them. Bug 675767 has
identified a site (foxsports.com) with articles/links that do have this
issue. The issue is repeatable for those pages and they are never
succeeding. I end-to-end tested this change with logging to confirm
we do repeatably see entry count going to 2 and that with this change
the pages can background load successfully.
