perf trace: Use the autogenerated mmap 'prot' string/id table

No change in behaviour:

And you can as well tweak 'perf trace's output to more closely match
strace's:

  # perf config trace.show_arg_names=no
  # perf config trace.show_duration=no
  # perf config trace.show_prefix=yes
  # perf config trace.show_timestamp=no
  # perf config trace.show_zeros=yes
  # perf config trace.no_inherit=yes
  # perf trace -e mmap sleep 1
