test/vhost: Extend fio runtime during migration tests

Migration can take longer than 10s, hence we need to give fio more
time to spin in order to make sure it's still running on the target
vm after migration is complete.

On the other hand, reduce the timeout used to wait for fio after
the migration is done - there's no need to wait almost a minute,
half that time.
