RFR: 8288907: serviceability/jvmti/vthread/SuspendResume1/SuspendResume1.java fails with -XX:TieredStopAtLevel=2,3

[Serguei Spitsyn]

The test SuspendResume fails on linux-aarch64 with timeouts.
However, it never fails when test timeout is set to a bigger value:

I'd like to push this as a trivial fix.

Testing: Submitted mach5 test runs on multiple platforms.
