perf trace: Allow suppressing the syscall argument names

To show just the values:

Default:

  # trace -e open*,close,*sleep sleep 1
  openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC           ) = 3
  close(fd: 3                                                           ) = 0
  openat(dfd: CWD, filename: /lib64/libc.so.6, flags: CLOEXEC           ) = 3
  close(fd: 3                                                           ) = 0
  openat(dfd: CWD, filename: /usr/lib/locale/locale-archive, flags: CLOEXEC) = 3

  close(fd: 1                                                           ) = 0

Remove it:

  # perf config trace.show_arg_names=no
  # trace -e open*,close,*sleep sleep 1
