perf trace: Update beautifier script for clone flags

Browse Source 
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",
