Add a shell test that verifies the file_offset diagnostic messages work correctly when perf encounters corrupted events. The test corrupts a MMAP2 event's size field in a recorded perf.data file, then checks that perf report produces warning messages that include both the file offset (e.g. "at offset 0x2738:") and the event type name with numeric id (e.g. "MMAP2 (10)"). This exercises the diagnostic improvements from the file_offset series, which retrofitted all skip/stop/error messages to include the position and type of the problematic event.
