perf annotate: Show group event string for stdio
When we enable the group, for tui/stdio2, the output first line includes
the group event string. While for stdio, it will show only one event.
For example,
perf record -e cycles,branches ./div
perf annotate --group --stdio
Percent | Source code & Disassembly of div for cycles (44407 samples)
......
The first line doesn't include the event 'branches'.
With this patch, it will show the correct group even string.
perf annotate --group --stdio
Percent | Source code & Disassembly of div for cycles, branches (44407 samples)
......
