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.
