device-crash-test: Remove problematic language

Replace "whitelist" in the device-crash-test script with
"rule list".

I'm using "rule list" instead of "allow list" or "pass list"
because the list is not used only for expected/allowed errors.
It also contain rules specifying which errors shouldn't be
ignored and/or should be fatal.
