  tsan: disable bench_threads.cpp on aarch64

The new test started failing on bots with:

CHECK failed: tsan_rtl.cpp:327 "((addr + size)) <= ((TraceMemEnd()))"
   (0xf06200e03010, 0xf06200000000) (tid=4073872)

This is a latent bug in aarch64 virtual address space layout,
there is not enough address space to fit traces for all threads.
But since the trace space is going away with the new tsan runtime
(D112603), disable the test.
