Bug 20222: Make bread crumb for cleanborrowers.pl match the link text in tools-home.pl

Bug 20222: Make bread crumb for cleanborrowers.pl match the link text in tools-home.pl

This patch revises the breadcrumbs in the template for batch patron
deletion / anonymization so that they match the text used in the tools
menu and on Tools home.

To test, apply the patch and go through a batch patron anonymization
process. At each step the breadcrumbs should read "Batch patron
deletion/anonymization" instead of "clean patron records."
