tests: integration: deployments: increase deployment status wait time

Applying updates takes a while, and since we've increased a number of jobs run
in parallel timeouts in MenderAPI.deployments.check_expected_status() are
popping up more frequently that desired. Increse the wait time to 180s and
reduce poll frequency to 1/s.
