Cataloging admins have inconsistent permissions on Vandelay Record Display Attributes

[Jane Sandberg]

In Concerto, user br1dbeck is a Cataloging Admin. The permissions for this user related to the vandelay record display attributes are inconsistent.

For bibliographic records, the user has: CREATE_BIB_IMPORT_FIELD_DEF and UPDATE_BIB_IMPORT_IMPORT_FIELD_DEF. But not DELETE_BIB_IMPORT_IMPORT_FIELD_DEF.

For authority records, the user has: UPDATE_AUTHORITY_IMPORT_IMPORT_FIELD_DEF and DELETE_AUTHORITY_IMPORT_IMPORT_FIELD_DEF. But not CREATE_AUTHORITY_IMPORT_IMPORT_FIELD_DEF.

I assume that cataloging admins should just receive all 6 of these permissions. If so, it should be relatively simple to:
1. add them to the list of permissions around line 2300 in Open-ILS/src/sql/Pg/950.data.seed-values.sql
2. add a database migration to update this in existing systems
