Bug 20707: Replace circ/search.pl circulate permission requirement with catalogue

To test:
 1 - Setup a staff patron with permissions:
   - catalogue
   - reserveforothers
   - course_reserves
 2 - Log in to staff client as that patron
 3 - Find a record and click to place a hold
 4 - Type more than three letters into the search bar but don't submit
 5 - Note that you will not receive autocomplete results
 6 - Either submit, or try to visit any page in staff client
 7 - Your session has been expired, you must log in again
 8 - Log in, go to course reserves
 9 - As before, trigger the autocomplete search in the instrcutor field
10 - Again your session has been terminated
11 - Apply patch
12 - Repeat above actions, this time you will not be kicked out
