Merging patrons only required edit_borrowers permission
but would result in a patron deletion.
This patch requires a new merge_borrowers subpermission
To test:
1. Give a patron the following permissions
catalogue, edit_borrowers, list_borrowers
2. Log into the staff interface as the patron
3. Do a patron search and select 2 patrons
4. Click merge patron - success - a patron got deleted
5. Apply patch, updatedatabase and restart_all
6. Repeat steps 3 and 4 - you can't
7. Add the new permission for merge_borrowers
8. Repeat steps 3 and 4 - now you can
9. prove t/Koha/Auth/Patrons.t
