ovs-ctl: Don't run "ovs-save save-flows" on fake bridges.

Previously, ovs-ctl would determine which bridges to run "ovs-save
save-flows" on by running "ovs-vsctl list-br".  In addition to real
bridges, that command also returns fake bridges.  An error is returned
when "ovs-save save-flows" is run on a fake bridge.  By using the newly
added "--real" flag to "ovs-vsctl list-br", we can get rid of that
unnecessary warning.
