perf report: Fix --stdio output alignment when --showcpuutilization used
Current perf report output is broken if --showcpuutilization is used.
Combination with -n and/or --show-total-period make things worse.
This patch fixes it as follows:

48.25% 48.25% 0.00% sleep [kernel.kallsyms] [k] trace_hardirqs_off
34.99% 34.99% 0.00% sleep [kernel.kallsyms] [k] __find_get_block_slow
15.99% 15.99% 0.00% sleep [kernel.kallsyms] [k] lock_release_holdtime
