Bug 8981 - Remove Nonpublic General Note from OPAC authorities display

Currently, the MARC21 667 Nonpublic General Note field is appearing on the opac-authoritiesdetail.pl page.

Since it is a nonpublic note, it makes sense to remove it from this view.

This patch adds in an extra condition that checks authority records for MARC21 667 fields before displaying them in this opac screen.
