Tempest: increase ironic sync timeout

Increase ironic_sync_timeout to 80 sec. Ironic default status check period
is 60 sec. But calling Ironic API to get node status takes some time, and
races appear, as result tempest job periodically fails. 80 sec would
be more than enough to make one more check.
