[libcxx-commits] [libcxxabi] [libcxxabi][test][VE] Relax test configucation (PR #67387)

[Kazushi Marukawa via libcxx-commits]

https://github.com/kaz7 created https://github.com/llvm/llvm-project/pull/67387

Relax test configuration for VE.  VE limits the number of threads per a process up to 64.  So, it is needed to relax number of threads test configuration.  Otherwise, we get temporary resource exhausted errors at thread creation.
