RFR: 8323066: gc/g1/TestSkipRebuildRemsetPhase.java fails with 'Skipping Remembered Set Rebuild.' missing

[Thomas Schatzl]

Hi all,

  the test is too sensitive to the amount of allocation, using an arbitrary value of G1MixedGCLiveThresholdPercent. This caused random test failures depending on how objects were allocated after GC in old gen, and the amount of allocations during startup.

Using a value of 0 should guarantee that no old region will ever be selected for rebuild, resulting in the correct expected message.

Testing: local testing of test case, gha

Thanks,
  Thomas
