perf stat: Print topology/time headers with --metric-only
When --metric-only is enabled there were no headers for the topology in
interval mode. Also when headers were printed they were on a separate
line.
Before:
$ perf stat --metric-only -A -I 1000 -a
1.001038376 frontend cycles idle insn per cycle stalled cycles per
insn branch-misses of all branches
1.001038376 CPU0 123.54% 0.23 5.29
7.61%
1.001038376 CPU1 137.78% 0.24 5.13
10.07%
1.001038376 CPU2 64.48% 0.22 5.50
6.84%
After:
$ perf stat --metric-only -A -I 1000 -a
1.001111114 CPU0 82.46% 0.32 2.60
7.64%
1.001111114 CPU1 126.63% 0.02 42.83
0.15%
1.001111114 CPU2 193.54% 0.32 2.59
6.92%
