vport-netdev: Use vport stats layer on 32-bit machines.

Linux devices store stats in counters the size of a machine word,
which are rapidly overflowed on a 32-bit machine.  In this
situation we now use the vport stats layer, which always uses 64-
bit stats.  On 64-bit machines we continue to use the normal
Linux stats to avoid the extra overhead of counting twice.
