Bug 30939: Fix use statement for DelAuthority
Without this patch, the script won't delete any
unused authorities, but gives an error instead
and dies:

Undefined subroutine &main::DelAuthority called at ./misc/migration_tools/remove_unused_authorities.pl line 98.

To test:
- Run from koha-shell:
  ./misc/migration_tools/remove_unused_authorities.pl -t
- Verify several authorities are reported as unused
- ./misc/migration_tools/remove_unused_authorities.pl -c
- Verify the error message is shown when the first unused
  authority is found and the script stops
- Apply patch and rerun:
  ./misc/migration_tools/remove_unused_authorities.pl -t
- Verify the error is gone, the script finishes and auhorities
  are deleted

$0: Remove unused authority records
This script removes authority records that do not have any biblio
records attached to them.
If the --aut option is supplied, only authority records of that
particular type will be checked for usage. --aut can be repeated.
If --aut is not supplied, all authority records will be checked.
Use --confirm Confirms you want to really run this script, otherwise prints this help.
Use --test to perform a test run. This script does not ask the
operator to confirm the deletion of each authority record.
parameters
--aut|authtypecode TYPE the list of authtypes to check
--confirm or -c confirm running of script
--test or -t test mode, don't delete really, just count
--help or -h show this message.
