perf test: test_intel_pt.sh: Add per-thread test
When tracing the kernel with Intel PT, text_poke events are recorded per-cpu. In per-thread mode that results in a mixture of per-thread and per-cpu events and mmaps. Check that happens correctly. The debug output from perf record -vvv is recorded and then awk used to process the debug messages that indicate what file descriptors were opened and whether they were mmapped or set-output.
