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
Disassembly of section .text:

_raw_spin_lock():
EXPORT_SYMBOL(_raw_spin_trylock_bh);
#endif
