Subject: [PATCH v2 0/2] perf test: Display remaining tests while waiting

The v1 patch series:
https://lore.kernel.org/lkml/20240405070931.1231245-1-irogers@google.com/
was partially merged. The check_if_command_finished wasn't working as
intended as stdout/stderr could be lost due to waitpid being
called. Modify this function to not use waitpid and use procfs
instead.

Keeping the output test display logic in 1 place should simplify
improving parallel and sequential output. Namhyung was experiencing
issues with this in:
https://lore.kernel.org/lkml/20240628215751.1512250-1-namhyung@kernel.org/

  tools subcmd: Add non-waitpid check_if_command_finished()
