vmtest-sync-images: update the URL of the maas streams

The old URL goes through a couple of redirects but does not land at the
correct location.

CI is failing for the exact problem this MP fixes.

[Paride Legovini (paride)]

Which is normal as the sync-images stage is *not* part of the CI run, it happens before it, and it's done by Jenkins with whatever is already on master.

[Ryan Harper (raharper)]

I'm +1 on this; did we file an RT or some thing to let them know the old URL does not get to the right place?

We may need to pull and push this directly to master if the autolander is going to fail as well.

I notified in #maas about the URL breaking. I'm pushing this branch to master so we can autoland again.
