perf annotate: Use the default annotation options for --stdio2

With an empty '[annotate]' section in ~/.perfconfig:

  # perf record -a --all-kernel -e '{cycles,instructions}:P' sleep 5
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 2.243 MB perf.data (5513 samples) ]
  # perf annotate --stdio2 _raw_spin_lock | head -20
