Bug 21397: Mark "Routing list" tab as active when selected

Bug 21397: Mark "Routing list" tab as active when selected

/members/routing-lists.pl?borrowernumber=5 show the different tab of the
menu but "Routing lists" is not displayed as the selected one (active).

"routinglistview" must be set and passed to the template

Test plan:
Enable the RoutingSerials pref
and hit /members/routing-lists.pl?borrowernumber=42

The "Routing lists" tab must be selected/active

Followed test plan and tab now shows as active.
