Disable ztest deadman timer

The ztest deadman timer has been causing false positives in the testing VMs. To make it easier to spot possible regressions I'm disabling this timer. The buildbot test infrastructure will still mark ztest instances which take to long to complete as failures. Signed-off-by: Brian Behlendorf <[email protected]> Issue openzfs#1018
