RFR: 8349192: jvmti/scenarios/contention/TC05/tc05t001 fails: ERROR: tc05t001.cpp, 281: (waitedThreadCpuTime - waitThreadCpuTime) < (EXPECTED_ACCURACY * 1000000)

[Serguei Spitsyn]

This is fix is to increase the `EXPECTED_ACCURACY` value in the test:
 `hotspot/jtreg/vmTestbase/nsk/jvmti/scenarios/contention/TC05/tc05t001`.
It is used check that the waiting time between `MonitorWait` and `MonitorWaited` event is not big. It seems that in some corner cases this time can be bigger than expected.

Testing:
 - TBD: Verify the test with mach5 test runs
