Description
The check for signal handlers being changed is used in the hs_err report, "jcmd VM.info" output, and periodically with -Xcheck:jni

We should have a test that it does not contain any warnings under "normal" circumstances.

Fix request (11u) I am backporting this for parity with 11.0.18-oracle. Low risk as it affects tests only. Patch applies cleanly. Test passes manually. Tier 1 passed with GH actions.
