ovs-ofctl: Add "out_group" keyword for OF1.1+ matching on output group.

It seems that OVS has never supported this OpenFlow feature in ovs-ofctl,
which makes it hard to test.  This commit adds support.

(Open vSwitch has supported this in OpenFlow for a long time; it's only
ovs-ofctl that didn't.)
