Revert "gnu: guile-static-stripped: Update to 2.2."

As discussed on IRC, keeping bootstrap Guile on 2.0 simplifies adding new
architectures and removes the need for parameterizing
gnu/packages/bootstrap.scm.

This reverts commit 2acfe022a740f79b593348cc6362cc4ee8f33bb4.

* gnu/packages/make-bootstrap.scm (%guile-static): Revert to guile-2.0.  Retain
build recipe.
* gnu/packages/patches/guile-relocatable.patch: Update for Guile 2.0.14.
