Subject: [PATCH v2 1/3] perf test: Add a shell wrapper for "Setup struct perf_event_attr"

The "Setup struct perf_event_attr" test in attr.c does a bunch of
directory finding to set up running a python test that in general is
more brittle than similar logic we have in shell tests. Add a shell
test that invokes and runs the tests in the python attr.py script.
