perf test: Do not fail Intel-PT misc test w/o libpython

The virtual 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.
