distro: Use the bootstrap Guile for the derivation of sources.

* distro/packages/base.scm (bootstrap-origin,
  package-with-bootstrap-guile): New procedures.
  (gnu-make-boot0, diffutils-boot0, findutils-boot0, binutils-boot0,
  gcc-boot0, linux-libre-headers-boot0, glibc-final, bash-final,
  guile-final): Use `package-with-bootstrap-guile'.
  (gcc-boot0-wrapped): Clear `source'.

* guix/ftp.scm (ftp-fetch): Add a #:guile keyword parameter.  Honor it.
* guix/http.scm (http-fetch): Likewise.
