perf tools fixes for v5.16: 2nd batch

- Fix SMT detection fast read path on sysfs.

- Fix memory leaks when processing feature headers in perf.data files.

- Fix 'Simple expression parser' 'perf test' on arch without CPU die topology
  info, such as s/390.

- Fix building perf with BUILD_BPF_SKEL=1.

- Fix 'perf bench' by reverting "perf bench: Fix two memory leaks detected with ASan".

- Fix itrace space allowed for new attributes in 'perf script'.

- Fix the build feature detection fast path, that was always failing on systems
  with python3 development packages, speeding up the build.

- Reset shadow counts before loading, fixing metrics using duration_time.

- Sync more kernel headers changed by the new futex_waitv syscall: s390 and powerpc.
