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

After:
