Some updates for module-based Go builds.

Update lf to r13 as a testbed for making module support work.

Here is what works:

- building a Go module without external dependencies
- "make patch && make show-go-modules" shows a list of dependency
  files.

What does not:

- adding the lines from "make show-go-modules" to the Makefile does
  nothing.
- "make stage-install" does not do the right thing.
