[jdk21u] RFR: 8339869: [21u] Test CreationTime.java fails with UnsatisfiedLinkError after 8338884

[Goetz Lindenmaier]

Running one test as /othervm makes sure the lib is not loaded twice in the same VM

Testing:
The failure was sporadic, but we saw it in our 4 daily test runs (21u, 21u-dev, 17u, 17u-dev) about once a day. Since adding this fix temporary to the four test setups on September 3rd, we have not encountered the problem again.
