ipcpd: Fix timerwheel test

Sometimes the timerwheel test could fail because of scheduler timings
(an issue more apparent in Virtual Machines). When the first check
fails, the test will wait for another complete round of the
timerwheel.  The maximum number of slots in the test is reduced to
reduce the test time.
