    NEGCACHE: Add root's uid/gid to ncache
    
    As "root" is not handled by SSSD, let's add its uid and gid to the
    negative cache as well. The reason it's added without specifying a
    domain is to follow how the negative cache is used by cache req's code
    when searching something by id.
    
    As the negative cache check for uid/gid, in the cache req code, is done
    after resolving the name, we can save one LDAP call to the data
    provider.
