An embarrassing mistake :/

I still had gnu/packages/javascript.go in my source tree, so I didn't
notice the problem until I tried building Guix on another machine.

I ended up doing `make clean-go && rm gnu/packages/*.go`, and I was
surprised by how many old modules I had lying around. I will get into
the habit of doing this more often.
