Add another extraneous neverallow rule to force attribute inclusion

Due to the massively increased number of attributes in SELinux policy
as part of the treble changes, we have had to remove attributes from
policy for performance reasons.  Unfortunately, some attributes are
required to be in policy to ensure that our neverallow rules are being
properly enforced.  Usually this is not a problem, since neverallow rules
indicate that an attribute should be kept, but this is not currently the
case when the attribute is part of a negation in a group.

This is particularly problematic with treble since some attributes may
exist for HALs that have no implementation, and thus no types.  In
particular, this has caused an issue with the neverallows added in our
macros.  Add an extraneous neverallow rule to each of those auto-generated
neverallow rules to make sure that they are not removed from policy, until
the policy compiler is fixed to avoid this.  Also add corresponding rules
for other types which have been removed due to no corresponding rules.
