perf/x86/intel: Hide TSX events when RTM is not supported
0day testing reported a perf test regression on Haswell systems without
RTM. Commit a5df70c35 hides the in_tx/in_tx_cp attributes when RTM is not
available, but the TSX events are still available in sysfs. Due to the
missing attributes the event parser fails on those files.
Don't show the TSX events in sysfs when RTM is not available on
Haswell/Broadwell/Skylake.
Fixes: a5df70c354c2 (perf/x86: Only show format attributes when supported)
