Revert of bookmarks: Remove url_database.h entry from DEPS list.

Revert of bookmarks: Remove url_database.h entry from DEPS list. (patchset #2 id:20001 of https://codereview.chromium.org/912653005/)

Reason for revert:
Seem to cause a failure related to bookmark dependencies.

Original issue's description:
> bookmarks: Remove DEPS file now that componentization is almost done.
>
> Since the componentization of bookmarks is mostly done, we don't need the rules forbidding usage of //chrome/browser anymore, as the files still in
> //chrome/browser/bookmarks won't be moved in the component  (factories,
> client, etc, all belongs to the embedder, not the component).

I see the below dependency failure 
ERROR in
/mnt/data/b/build/slave/Linux_Tests/build/src/chrome/browser/bookmarks/bookmark_html_writer_unittest.cc
  Illegal include: "chrome/utility/importer/bookmark_html_reader.h"
    Because of "-chrome" from chrome's include_rules.

This started happening after the CL landed.
