Make startup hooks kind of work with native AOT

[MichalStrehovsky]

Fixes #96052.

Filed #97020 on the System.IO test.

exit code 137 means SIGKILL Killed eg by kill
ulimit -c value: 0
Unable to obtain kernel buffer: Operation not permitted
usage: sudo dmesg
----- start =============== XUnitLogChecker Output =====================================================
No dumps found in /cores.

This seems to be happening quite frequently in the CI. I have opened #97049 to have it tracked.
