Subject: [PATCH] test: add an indicator `isIBMi`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have to skip some test cases on IBM i.
On IBM i, process.platform and os.platform() both return aix,
It is not enough to differentiate between IBM i and real AIX system.
Also updated parallel/test-cluster-bind-privileged-port.js for test.
