perf stat: Don't print bogus data on -e instructions
When only the instructions event is requested:
$ perf stat -e instructions git s
M builtin-stat.c
Performance counter stats for 'git s':
917,453,420 instructions # 0.00 insns per cycle
0.213002926 seconds time elapsed
The 0.00 insns per cycle comment in the output is totally bogus and
misleading. It happens because update_shadow_stats() doesn't touch
runtime_cycles_stats when only the instructions event is requested. So,
omit printing the bogus data altogether.
