Bug 16777: Correct intranet search alias

Bug 16777: Correct intranet search alias

A long-standing typo in our apache config files:
[intranet]/search refers to search.pl (which does not exist)

This patch refers it to catalogue/search.pl

Test plan:
Run an install or copy the change from apache-shared-intranet.conf or
koha-httpd.conf to your apache config. Restart Apache and check
if http://[your staff client]/search works.

Tested by making manual changes according to the patch. Did not test a
new installation.
