This allows the OAI-PMH service to not provide item information when
there is a rule that would supress it in OpacHiddenItems.
Test plan:
* Find an OAI-PMH URL that shows you some items.
* Add an entry to OpacHiddenItems that would block that.
* Check that it's blocked.

Tested, playing with OpacHiddenItems. GetRecord OAI verb returns a record
complying with OpacHiddenItems rules, for example without items from a specific
library.
