[PATCH v2] perf test: Do not fail Intel-PT misc test w/o libpython

From: Namhyung Kim
Date: Fri Oct 21 2022 - 14:11:11 EST


The virtuall LBR test uses a python script to check the max size of
branch stack in the Intel-PT generated LBR. But it didn't check whether
python scripting is available (as it's optional).

Let's skip the test if the python support is not available.

Fixes: f77811a0f625 ("perf test: test_intel_pt.sh: Add 9 tests")
