RFR: 8316001: GC: Make TestArrayAllocatorMallocLimit use createTestJvm

[Leo Korinth]

Make TestArrayAllocatorMallocLimit use createTestJvm (so that the test forwards VM/JAVA_OPTIONS). It seems there is no problem to propagate `-XX:+UnlockExperimentalVMOptions`.

Tested with:
`make run-test TEST=open/test/hotspot/jtreg/gc/arguments/TestArrayAllocatorMallocLimit.java` (PASS 1)
`make run-test TEST=open/test/hotspot/jtreg/gc/arguments/TestArrayAllocatorMallocLimit.java JTREG="JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions"` (PASS 1)

Started hs_tier1-5 to see that we do not propagate conflicting flags.
