Neverallow rules for ioctl extended permissions will pass in two
cases:
1. If extended permissions exist for the source-target-class set
the test will pass if the neverallow values are excluded.
2. If extended permissions do not exist for the source-target-class
set the test will pass if the ioctl permission is not granted.
