tests: Change ct zone UUID->name migration test to use GW routers.

The test added by 5a1d82c ("controller: Migrate from ct zone UUID
name to component name") was, in theory, correct.  However, due to the
way conditional monitoring works, the test cannot pass on deployments
where distributed routers are used.  These will initially not be
considered "local" datapaths, so ovn-controller will consider their CT
zone entries as stale:

Change the test instead and make it use gateway routers.  Like that the
behavior is known to be correct and we can, at least, ensure it won't be
broken in the future.
