perf config: Show the configuration when no arguments are provided

Browse Source 
More convenient thah having to recall what letter is about
showing/listing/dumping the configuration, i.e. no arguments means
-l/--list:

  # perf config
  llvm.dump-obj=true
  trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  trace.show_zeros=yes
  trace.show_duration=no
  # perf config -l
  llvm.dump-obj=true
  trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  trace.show_zeros=yes
  trace.show_duration=no
  # perf config -h

   Usage: perf config [<file-option>] [options] [section.name[=value] ...]

      -l, --list            show current config variables
          --system          use system config file
          --user            use user config file
