apparmor: reserve and mask off the top 8 bits of the base field
The top 8 bits of the base field have never been used, in fact can't
be used, by the current 'dfa16' format. However they will be used in the
future as flags, so mask them off when using base as an index value.
Note: the use of the top 8 bits, without masking is trapped by the verify
checks that base entries are within the size bounds.
