self: Drop support for Guix < 0.15 on Guile 2.0.
* guix/self.scm (false-if-wrong-guile, package-for-guile): Remove. (specification->package): Remove "guile2.0-" variants. (compiled-guix): #:guile-for-build defaults to (default-guile). Use 'specification->package' instead of 'package-for-guile'. (guile-for-build): Remove. (guix-derivation): Use 'default-guile' instead of 'guile-for-build'. Check whether we're running on Guile 2.0 with PULL-VERSION < 1.
