Bug 26133: Remove GetMarc* calls in detail.pl

Bug 26133: Remove GetMarc* calls in detail.pl

There are several calls in catalogue/detail.pl that can be removed:
GetMarcISBN, GetMarcAuthors, GetMarcSubjects, GetMarcSeries, GetMarcUrls and GetMarcHosts
They pass a variable to the template that is never used.

Test plan:
Confirm that this TT variable is never used.
