tools beauty: Add script to generate table of mmap's 'prot' argument



Will be wired up in the following csets:

  $ tools/perf/trace/beauty/mmap_prot.sh
  static const char *mmap_prot[] = {
  	[ilog2(0x1) + 1] = "READ",
  #ifndef PROT_READ
  #define PROT_READ 0x1
  #endif
  	[ilog2(0x2) + 1] = "WRITE",
  #ifndef PROT_WRITE
  #define PROT_WRITE 0x2
  #endif
  	[ilog2(0x4) + 1] = "EXEC",
  #ifndef PROT_EXEC
  #define PROT_EXEC 0x4
  #endif
  	[ilog2(0x8) + 1] = "SEM",
  #ifndef PROT_SEM
  #define PROT_SEM 0x8
  #endif
  	[ilog2(0x01000000) + 1] = "GROWSDOWN",
  #ifndef PROT_GROWSDOWN
  #define PROT_GROWSDOWN 0x01000000
  #endif
  	[ilog2(0x02000000) + 1] = "GROWSUP",
  #ifndef PROT_GROWSUP
  #define PROT_GROWSUP 0x02000000
  #endif
  };
