[PATCH v2 7/7] perf trace: Update beautifier script for clone flags

[Namhyung Kim]

According to the change in the sched.h, update the script to generate
the flags array like below.  Note that '+1' is needed to detect bitmask
pattern at index 0.

  $ cat tools/perf/trace/beauty/generated/clone_flags_array.c
  static const char *clone_flags[] = {
  	[32 + 1] = "CLEAR_SIGHAND",
  	[33 + 1] = "INTO_CGROUP",
  	[34 + 1] = "AUTOREAP",
  	[35 + 1] = "NNP",
  	[36 + 1] = "PIDFD_AUTOKILL",
  	[37 + 1] = "EMPTY_MNTNS",
  };

This was found by Sashiko during review.
