Reschedule airship feature builds 1 hour earlier

Reschedule the airship master feature tests build to be one hour
earlier. Overnight in the Kna1 region in CityCloud, we see webhook
failures caused by poor performance of the instances. This build has
been rescheduled a couple of times, but we're still hitting this on the
overnight and not in the daytime, so let's push the start time back one
hour to 1700 UTC, which is 2000 Finnish summer time.
