ci-ppc64le: disable sanitizer test

The latest Ubuntu docker container on ppc64le has caused the sanitizer
tests to start failing within the PLDM repository. Until we can figure
this out, disable these tests on ppc64le machines.

See openbmc/openbmc-build-scripts#31 for details

Tested:
- Verified PLDM repo now passes CI on ppc64le machine
