s4-torture: take privileges into account in BASE-MAXIMUM_ALLOWED
The correct answer depends on the users privileges.
commit 4e3ea9e0da8e2f7d99b76114da4bca46c15d188c

idl: added bit definition for privilege masks
When you have backup or restore privileges, you automatically get
extra access bits in ACL interpretation. This adds definitions for the
bits you get.
