Bug 32416: Update attribute number for arp search to 9015

Bug 32416: Update attribute number for arp search to 9015

Bug 20078 updated the attribute for arp to 2014 to avoid conflict with 9013 not-on-loan-count

Bug 28830 then added Control-number-identifier as 2014, breaking arp again

This patch updates the number to 9015

To test:
1 - Apply first patch
2 - Attempt searching by arp, no results (add a unique 526$d to a record to ease searching)
3 - Apply this patch
4 - Copy bib1.att and ccl.properties to the correct locations
    cp etc/zebradb/biblios/etc/bib1.att /etc/koha/zebradb/biblios/etc/bib1.att
    cp etc/zebradb/ccl.properties /etc/koha/zebradb/ccl.properties
5 - Restart zebra
6 - Rebuild indexes
7 - Search again, success!
