Hello! Just ran into this. I think we also need to pass in errno
here to strerror instead of err:

Currently, the error output without a base btf reads:
$ bpftool btf dump id 816
Error: get btf by id (816): Unknown error -22
When it should (or at least intends to) read:
$ bpftool btf dump id 816
Error: get btf by id (816): Invalid argument
I was going to send this patch but if a v2 is going to be sent, figured
I mention it. Thanks!
