Most likely, "pkg-config" should be in native-inputs.

I believe there's a linter that checks whether packages should
be in native-inputs, but I'm not sure if pkg-config is detected.
Consider running ./pre-inst-env guix lint go-github-com-google-gousb.

Also, why is "libusb" in "propagated-inputs" and not in "inputs"?
"inputs" is usually preferred over "propagated-inputs", but there
are valid reasons to use "propagated-inputs" instead.
