RFR: 8348324: The failure handler cannot be build by JDK 24 due to restricted warning

[Magnus Ihse Bursie]

GatherProcessInfoTimeoutHandler calls System.loadLibrary, which will trigger a `restricted` warning when building with JDK 24 or newer, and failing the build.

This should be fixed by adding a @SuppressWarnings("restricted").
