Bug 22580: Remove deprecated delete_expired_opac_registrations.pl cronjob

Removes the deprecated script and changes the hint on the
PatronSelfRegistrationExpireTemporaryAccountsDelay sytem preference.

To test:
- Make sure the script misc/cronjobs/delete_expired_opac_registrations.pl
  was deleted
- Make sure the hint on the PatronSelfRegistrationExpireTemporaryAccountsDelay
  system preference is correct
- Make sure there are no other reference to the removed script
