Bug 32205: Remove unnecessary syspref template params for failed OPAC auth

This patch removes some unnecessary syspref template params for
failed OPAC auth. The templates handle these syspref using the
Koha.Preference() TT plugin function, so they're completely redundant
and just make checkauth() longer than it needs to be.

Test plan:
1) Apply patch
2) Enable OpacCloud, OpacBrowser, and OpacTopissue sysprefs
3) koha-plack --restart kohadev
4) Log out of Koha if you're logged in
5) Go to http://localhost:8080/cgi-bin/koha/opac-user.pl
6) Note that you can see the Cart as well as links for the following:
