When fetching origins from the quota database, include the ones where the modification time exactly matches the beginning.

This includes origins with modification time 0 in the result when fetching origins "since the beginning of time".

BUG=134825
TEST=content_unittests:QuotaDatabaseTest.OriginLastModifiedSince; manual: Database storage is deleted from the Clear Browsing Data dialog.

This change lgtm...

But are we not setting the last modified timestamp properly in some "Database
storage" cases? Which kind of databases? Is there some other issue at the root
of 134825?

In the profile I looked at, it seemed like web databases and file systems. Not
sure if there are others.

If you want to investigate, I can send you the profile.
