scripts/unit-test: Detect problematic sanitizers

Instead of permanently blacklisting sanitizers from running in our unit
test environment for all powerpc platforms, run a problematic test case
to determine if we can use the sanitizers or not.

Tested:
    Ran on amd64 and ppc64el to verify that sanitizers are still run on
    the currently working amd64 and not on the currently broken ppc64el.
