self: Produce a complete package with the 'guix' command.
* guix/self.scm (guix-command): New procedure. (compiled-guix): Add #:pull-version parameter. [command, package]: New variables. Honor PULL-VERSION. (guix-derivation): Add #:pull-version and pass it to 'compiled-guix'. * build-aux/build-self.scm (build-program): Add #:pull-version parameter. Pass it to 'guix-derivation'. (build): Add #:pull-version and pass it to 'build-program'. * build-aux/compile-as-derivation.scm: Pass #:pull-version to BUILD.
