perf tools: Add fallback for exclude_guest Commit 7b100989b4f6bce70 ("perf evlist: Remove __evlist__add_default") changed to parse "cycles:P" event instead of creating a new cycles event for perf record. But it also changed the way how modifiers are handled so it doesn't set the exclude_guest bit by default. It seems Apple M1 PMU requires exclude_guest set and returns EOPNOTSUPP if not. Let's add a fallback so that it can work with default events. Also update perf stat hybrid tests to handle possible u or H modifiers.

perf test: Add stat test for record and script When using the global aggregation mode, running perf script after perf stat record can result in a segmentation fault as seen with commit 8b76a3188b85 ("perf stat: Remove unused perf_counts.aggr field"). Add a basic test to the existing suite of stat-related tests for checking if that workflow runs without erroring out.

perf test: Add a test for default perf stat command Test that one cycles event is opened for each core PMU when "perf stat" is run without arguments. The event line can either be output as "pmu/cycles/" or just "cycles" if there is only one PMU. Include 2 spaces for padding in the one PMU case to avoid matching when the word cycles is included in metric descriptions.
