Subject: [PATCH] perf trace: Update beautifier script for clone flags

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[] = {
  	[ilog2(0x00000100) + 1] = "VM",
  	[ilog2(0x00000200) + 1] = "FS",
  	[ilog2(0x00000400) + 1] = "FILES",
  	[ilog2(0x00000800) + 1] = "SIGHAND",
  	[ilog2(0x00001000) + 1] = "PIDFD",
  	[ilog2(0x00002000) + 1] = "PTRACE",
  	[ilog2(0x00004000) + 1] = "VFORK",
  	[ilog2(0x00008000) + 1] = "PARENT",
  	[ilog2(0x00010000) + 1] = "THREAD",
  	[ilog2(0x00020000) + 1] = "NEWNS",
  	[ilog2(0x00040000) + 1] = "SYSVSEM",
  	[ilog2(0x00080000) + 1] = "SETTLS",
  	[ilog2(0x00100000) + 1] = "PARENT_SETTID",
  	[ilog2(0x00200000) + 1] = "CHILD_CLEARTID",
  	[ilog2(0x00400000) + 1] = "DETACHED",
  	[ilog2(0x00800000) + 1] = "UNTRACED",
  	[ilog2(0x01000000) + 1] = "CHILD_SETTID",
  	[ilog2(0x02000000) + 1] = "NEWCGROUP",
  	[ilog2(0x04000000) + 1] = "NEWUTS",
  	[ilog2(0x08000000) + 1] = "NEWIPC",
  	[ilog2(0x10000000) + 1] = "NEWUSER",
  	[ilog2(0x20000000) + 1] = "NEWPID",
  	[ilog2(0x40000000) + 1] = "NEWNET",
  	[ilog2(0x80000000) + 1] = "IO",
  	[ilog2(0x00000080) + 1] = "NEWTIME",
  	[32 + 1] = "CLEAR_SIGHAND",
  	[33 + 1] = "INTO_CGROUP",
  	[34 + 1] = "AUTOREAP",
  	[35 + 1] = "NNP",
  	[36 + 1] = "PIDFD_AUTOKILL",
  	[37 + 1] = "EMPTY_MNTNS",
  };
