[NETFILTER]: Use only 32bit counters for CONNTRACK_ACCT

Browse source 
Initially we used 64bit counters for conntrack-based accounting, since we
had no event mechanism to tell userspace that our counters are about to
overflow.  With nfnetlink_conntrack, we now have such a event mechanism and
thus can save 16bytes per connection.
