RFR: JDK-8201603: MonitorContendedEnter failure in nsk/jvmti/scenarios/contention/TC02/tc02t001

[Gary Adams]

The main thread in tc02t001 is using a sleep(100) to cause a
monitor contention for the debuggee thread. On some slower
platform builds the main thread continues before the debuggee
thread observes the contention.

Similar to the fix for cm02t001, this is a simple change to increase
the pauses to allow the debuggee thread to run.
