RFR: 8311306: Test com/sun/management/ThreadMXBean/ThreadCpuTimeArray.java failed: out of expected range

[Kevin Walls]

Trivial test update to run in "othervm".   This test has failed due to interrupted threads: the interruption interferes with timing, but also the test is designed to fail if interrupted.

Other tests in the same directory have the same requirement that threads/sleeps are not interrupted, and they run with othervm and are not known to fail.
