psql: Improve tab completion for GRANT/REVOKE 

This commit improves the handling of the following clauses:
- Addition of "CREATE" for ALTER DEFAULT PRIVILEGES .. GRANT/REVOKE.
- Addition of GRANT|ADMIN|INHERIT OPTION FOR for REVOKE, with some
completion for roles, INHERIT being added recently by e3ce2de.
- Addition of GRANT WITH ADMIN|INHERIT.

The list of privilege options common to GRANT and REVOKE is refactored
to avoid its duplication.
