Bug 19995: use Modern::Perl in Catalogue perl scripts

Test Plan:
- Check that it now says 'use Modern::Perl;' and not 'use strict; use
warnings;' in the following catalogue perl scripts.

MARCdetail.pl
export.pl
image.pl
imageviewer.pl
issuehistory.pl
labeledMARCdetail.pl
moredetail.pl
search.pl
showmarc.pl
updateitem.pl
