  [compiler-rt][xray] Disable fdr-reinit test on AArch64

We run bots on a shared machine and under high load
this test sometimes segfaults.

https://lab.llvm.org/buildbot/#/builders/185/builds/1368

==1952234==XRay FDR init successful.
==1952234==XRay FDR: Not flushing to file, 'no_file_flush=true'.
<...>fdr-reinit.cpp.script: line 4: 1952234 Segmentation fault
XRAY_OPTIONS="verbosity=1" <...>/fdr-reinit.cpp.tmp

Looking at the printed output I think it's happening at:
// Finally, we should signal the sibling thread to stop.
keep_going.clear(std::memory_order_release);

Disabling the test while I try to reproduce.
