James Clark 180fd0c1ea perf tests: Make leader sampling test work without branch event ...

Arm a57 only has speculative branch events so this test fails there. The
test doesn't depend on branch instructions so change it to instructions
which is pretty much guaranteed to be everywhere. The
test_branch_counter() test above already tests for the existence of the
branches event and skips if its not present.
