Bug 13458: Display the correct patron categories

Bug 9811 removes useful code.
Actually the AddPatronLists pref is not sent to the template from
members/member.pl.

To fix this issue, we can use the existing not clean way, or compare the
syspref value directly in the template. This second solution is
implemented in this patch.

Test plan:
1/ Set the AddPatronLists pref to 'specific'
2/ On the patron home page (members/members-home/pl), the patron search
result page (members/member.pl after launching a search) and on the
checkouts page/patron search result (circ/circulation.pl after searching
a patron using the check out), verify that the patron category list is
the specific ones.
3/ Test there are no regression with the AddPatronLists pref set to
'general'.

Works as described and fixes the problem.

Note: I am not sure if AddPatronLists makes sense -
if you set it to general patron types, it still preselects the
wrong category type (tried organization, a child patron category
was selected). Also the name is confusiong nowadays with the
Patron list feature.
