build-system/guile: Add target-guile-scm+go procedure.
The paths to .scm and .go files can be constructed given a guile version and a base directory. However it is few lines of code that needs to be copy&pasted. This new procedure returns both of them reducing the maintenance cost. * guix/build/guile-build-system.scm (target-guile-scm+go): New procedure.
