[contrib/playerctl]: don't log when no player is found

[ouuan]

playerctl status returns 1 when no player is found, which caused contrib/playerctl to log many times when there's no player.

Thanks a lot for the improvement!

Alternatively, cli.util.execute() has a parameter to ignore errors (ignore_errors=True), but your solutions works great, as well.

cli.util.execute with both ignore_errors=True and include_stderr=True doesn't return stderr when exit code is not zero. Is it expected?

Oh, that does sound like a bug :)
