John Johansen d79e57db45 apparmor: ensure that dfa state tables have entries ...

commit c27c6bd2c4 upstream.

Currently it is possible to specify a state machine table with 0 length,
this is not valid as optional tables are specified by not defining
the table as present. Further this allows by-passing the base tables
range check against the next/check tables.

Fixes: d901d6a298 ("apparmor: dfa split verification of table headers")
