The usual wemux.conf location is /usr/local/etc, but that directory doesn't
exist, so we patch the script to look in /etc.
---
I forgot I had manually created /usr/local/etc, but we can't assume the user
will know to do that. qyliss on #nixos said to put it in /etc.

Other comments were addressed.

I think he might have meant $out/etc? I don't believe /etc is a valid
build output location...

nit: it doesn't seem like rec is needed
