perf tests: Check python path on attr and binding test
Current perf test code tries to execute python version 2 in order to
test attributes on perf_event_open syscall. However it's not default
python version anymore a system can have python v3 only or v2 with a
different name (e.g. python2). So if there's no such python interpreter
with the name 'python', the test would fail like this (yes, it's
happened on my new archlinux laptop :).
13: struct perf_event_attr setup :sh: python: command not found
FAILED!
As we can pass name of the python interpreter on make, use it for
the attr test also.
