  [asan] Flush stderr in test (#114084)

This is the ASan equivalent of
https://github.com/llvm/llvm-project/pull/114083.

The x86_64_lam_qemu buildbots started failing

(https://lab.llvm.org/buildbot/#/builders/139/builds/5462/steps/2/logs/stdio).
Based on the logs, it appears the ASan check is correct but it did not
match the stderr/stdout output. This patch attempts to fix the issue by
flushing stderr as appropriate.
