Skip OOM-related tests on incompatible platforms. (#9386)

We only run OOM related tests on x86_64 and aarch64, as jemalloc on other
platforms (notably s390x) may actually succeed very large allocations. As
a result the test may hang for a very long time at the cleanup phase,
iterating as many as 2^61 hash table slots.
