Issue 50806 - Fix minor issues in lib389 health checks
Description: For permissions checks, add a list of permissions
that is acceptable instead of single value.
For RI plugin attribute indexing checks, we now check
if a container scope is specified. If it is set, we
skip all the other backends that are not in the scope.
This prevents false positives.
