perf tools: Fix missing feature check for inherit + SAMPLE_READ
It should also have PERF_SAMPLE_TID to enable inherit and PERF_SAMPLE_READ on recent kernels. Not having _TID makes the feature check wrongly detect the inherit and _READ support. It was reported that the following command failed due to the error in the missing feature check on Intel SPR machines. $ perf record -e '{cpu/mem-loads-aux/S,cpu/mem-loads,ldlat=3/PS}' -- ls Error: Failure to open event 'cpu/mem-loads,ldlat=3/PS' on PMU 'cpu' which will be removed. Invalid event (cpu/mem-loads,ldlat=3/PS) in per-thread mode, enable system wide with '-a'.
