Dependency links are broken

[tbaumgard (Tim Baumgard)]

​Commit d66d4aa "portlist: Drop unused library search method" broke the links that show up for a port's dependencies on the port list page because those links were still using the library search method. At the moment, no ports are displayed when clicking on a dependency link.

I thought at first that maybe the links could be updated to use the name search method if the library search method isn't used anywhere else anymore, but it turns out that method uses the LIKE operator rather than the = operator, making it show more ports than just the dependency. It might be best to simply revert this commit.
