  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")
