test: normalize known inspector crash as completion

[joyeecheung]

This works around a pre-existing inspector issue: if the debuggee exits too quickly the inspector can segfault while tearing down. For now normalize the trailing segfault as completion to keep the CI green until the upstream bug is fixed, since it only reproduces on some slow CI machines and is not what the probe tests care about.
