Subject: [PATCH] Disable folly_synchronization_distributed_mutex_test on ARM
 for now (#6126)

Summary:
This test is crashing on ARM but is not yet production code.
Let's not let it block ARM CI. See PR https://github.com/facebook/rocksdb/issues/5932
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6126

Test Plan:
./folly_synchronization_distributed_mutex_test, on Linux/ARM,
on Linux/x86_64, and with LITE=1 on Linux/x86_64 (also disabled)
