perf arm-spe: Correct sample flags for SPE event
Now it's hard code to set sample flags for CPU, TIME and TID for SPE event, which is pointless. The CPU is useful for sampling only for per-mmap case, it is used to indicate the AUX trace is associated to which CPU. The TIME sample is not needed for AUX event, since the time for AUX event is not really used and this time is a different thing from the timestamp in Arm SPE trace, the timestamp tracing which is controlled by Arm SPE's config bit. The TID sample is not useful for AUX event. This patch corrects the sample flags for SPE event, it only set CPU sample bit for per-cpu mmap case.
