Subject: tools/bpftool: Remove warning about PID iterator support
Patch-mainline: v5.9-rc1
Git-commit: 93776cb9ee91aeed43ba53dcec97ffed4ae6f1f7
References: bsc#1177028

Don't emit warning that bpftool was built without PID iterator support. This
error garbles JSON output of otherwise perfectly valid show commands.
