Bug 12701 - OPAC reading history still accessible by URL if turned OFF

If the opacreadinghistory system preference is turned off it is still
possible to navigate directly to the OPAC reading history page if you
know the URL. This patch adapts the fix for Bug 10595 (OpacTopissue page
still accessible when system preference is turned off) for
opac-readingrecord.pl

To test, log in to the OPAC and test the following conditions:

- With opacreadinghistory, navigating directly to
  /cgi-bin/koha/opac-readingrecord.pl should trigger a 404 error.

- With opacreadinghistory turned on there should be a working link to
  "your reading history" in the left-hand sidebar menu.
