Subject: [PATCH v3 1/2] selftests/amd-pstate: Fix broken paths to run workloads in amd-pstate-ut

In selftests/amd-pstate, tbench and gitsource microbenchmarks are
used to compare the performance with different governors. In Current
implementation relative path to run `amd_pstate_tracer.py` are broken.
Fixed this by using absolute paths.
