Revert of Resubmit: Add real file for AdNetworks DB

Revert of Resubmit: Add real file for AdNetworks DB (https://codereview.chromium.org/274563003/)

Reason for revert:
Linux Asan is failing with this patch: http://build.chromium.org/p/chromium.memory/builders/Linux%20ASan%20LSan%20Tests%20%282%29/builds/2483/steps/unit_tests/logs/stdio

Original issue's description:
> Resubmit: Add real file for AdNetworks DB
> 
> This is a resubmit of https://codereview.chromium.org/268063004/.
> 
> The previous version was reverted because it caused a memory leak. This was a
> problem with RefCounting from ui::ResourceBundle::LoadDataResourceBytes(), which
> has been fixed.
> 
> Details:
> Even though the method returns a non-refcounted ptr to a RefCountedStaticMemory
> (which according to the class comment, "the ref counting does not matter" [1]),
> the ref-counting _does_ matter. The fix for this went in as part of a refactor
> in https://codereview.chromium.org/263953003/.
> 
> [1] http://src.chromium.org/viewvc/chrome/trunk/src/base/memory/ref_counted_memory.h?revision=267321 line 44
