perf test test_intel_pt.sh: Test sample mode with event with PMU name

Browse Source 
br_misp_retired.all_branches is supported on processors that support
Intel PT, so use it to test sample mode with an event that has been
given a PMU name.

Please note, the test fails prior to the fix "perf parse-events: Do not
break up AUX event group".
