Bug 25777: Disable misleading datatables table information display z3950

This patch disables the table information display on z3950_search.pl,
since it only includes search result counts for that page, which is
misleading to end users.

To test:
1)  Do not apply the patch
2)  Do a Z39.50 search from cataloguing for "test" against Library of
    Congress.
3)  Note the bottom of the page says "Show 1 to 20 of 20" and
    "Showing page 1 of 501"
4)  Do a Z39.50 search from Acquisitions for "test" against Library of
    Congress (Acquisitions -> Vendor -> Basket -> Add to basket -> From
    external source).
5)  Apply the patch and restart Plack
6)  Repeat Step #2
7)  Note the bottom of the page now only says "Showing page 1 of 501"
8)  Note the search bar is gone
9)  Repeat step #4
10) Note the bottom of the page now only says "Showing page 1 of 501"
11) Note the search bar is gone
